Midrasz do Samuela I 30:17

...It is written (Ps. 119:62) At midnight do I constantly rise to give thanks unto Thee. Did David rise at midnight? Behold! He arose at the beginning of the night, for it is said, (Ib. ib. 147.) I came before thee in the twilight of night. And how do we know that the meaning of Neshef is the beginning of night? For it is written (Pr. 7, 9.) In the Neshef, in the evening of day. R. Oshiya said: "Thus [said David], 'I never passed half a night in sleep.'" R. Zerika said: "Until midnight he slumbered like a horse, thereafter he strengthened himself [fought sleep] like a lion." R. Ashi said: "Until midnight he was engaged in the study of the Torah ; after that [he spent his time] in songs and praises." And do you say Neshef means the beginning of night? Why do we find it used as the dawn of morning? For it is written (I. Sam. 30. 37.) And David smote them from the Neshef even unto the evening of the next day. Is it not meant from morning until evening? "Nay, from evening to evening." If so, then let it be written Me-haneshef Ad Haneshef or instead of Me-ha'ereb Ad Ha'ereb! [Why are the two words Neshef and Ereb, used for the same idea?] "But," says Raba, "Neshef means originally, 'The transition of anything' hence, night ends and day comes, the day ends and night comes." But how did David know the exact time at midnight? Behold! If Moses our teacher did not know it, for it is written (Ex. 11:4) Thus hath the Lord said, about midnight, etc. Why [does he come to say] about midnight? Should we say that he was told so by the Holy One, praised be He! Is there any possibility of God being in doubt? We must therefore explain it that Moses was told At midnight [as it really happened] ; but Moses [on his own recognizance] said About midnight; consequently we infer that Moses was in doubt. And how did David know it? David had a sign [which indicated the exact time at midnight to him], for R. Chana b. Bizna said in the name of R. Simon the Pious that: a harp was hanging over David's bed and, as soon as midnight arrived, a northerly wind blew in upon the strings of the harp and caused it to play. Thereupon, David arose and studied the Torah until dawn. At dawn the sages of Israel visited David and said to him : "Our Lord, O King! Israel, thy people need a living!" "Go and support yourselves by dealing with one another," replied David. "But," said they, "a handful does not satisfy the lion nor can a pit be filled with its own earth! [i. e., a community cannot live on its own resources]." Whereupon David said to them : "Go ye and stretch your hands out as a band [of warriors]. Immediately they held counsel with Achi'tophel and took advice from the Sanhedrin and inquired of the Urim and Tummim. R. Joseph said: "What is the passage [that refers to this]? It is written (I Chr.27, 34.) And after Achi'tophel (came) Joho'yada, the son. of Bena'yahu, and Ebya'thar, and the captain of the king's army was Joab, i.e., 'Achi'tophel' is the adviser; as it is said (II Sam. 16:23) And the council of Achi'tophel, which he counseled in those (Fol. 4a) days was as if a man had asked advice of the word of God : 'Jehoyada the son of Bena'yahu,' refers to the Sanhedrin; 'Ebyathar' refers to the Urim and Tummim ; as the passage said (Ib. 20, 23.) And Bena'yahu, the son of Jeho'yada was over the Kareithi and Peleithi. But why are the Sanhedrin called 'Kareithi ?' Because they cut their words clearly; and 'Peleithi?' Because their acts were wonderful [predestined]. And why was the name Urim given to the stones? Because they enlightened their words ; 'Tummim?' Because they finished their words.' And after this, they applied to Joab, the king's captain." R. Isaac b. Ada said : "What biblical passage relates to this? [That the harp was hanging over David's bed.] Awake! my spirit, awake! my psaltry and harp; I will wake up the morning dawn! (Ps. 57:9)." R. Zera said : "Moses, our teacher, knew very well [the exact time at midnight] and so did David; the harp was used not to tell him the time at midnight, but to awaken him from sleep. The reason for Moses' statement About midnight is that he feared lest the astrologers of Pharaoh might err in the time and would afterwards say that Moses lied ; as the master has said, Use thy tongue to say, I do not know lest you be found mistaken and deceived !' " R. Ashi said: "The time when Moses spoke was midnight (between the thirteenth and the fourteenth day of Nisan) and thus he said to Pharaoh: 'The Holy One, praised be He ! said, 'To-morrow, at this time, will I go out in the midst of Egypt.'"...

How important He is to us, David tells us in the verse: The Lord is my light and my salvation; whom shall I fear? (Ps. 27:1). When did David utter this verse? While fighting against the Amalekite bands. He fought against them at night and slew them, as it is said: And David smote them from the twilight even unto the evening (I Sam. 30:17). Who indeed lit the shooting stars and sent the lightning for them? R. Eleazar the son of Pedat was of the opinion that this verse refers to the war waged against the Egyptians after they pursued the Israelites. Observe what is written there: And there was the cloud and the darkness here, yet it gave light by night there (Exod. 14:20). R. Oshaya declared: When the Israelites saw the light they cried out: The Lord is my light and my salvation; whom shall I fear? The Holy One, blessed be He, said to Israel: If you light lamps before Me, I will illumine the world in your behalf with a great light, as it is said: But the Lord shall be unto thee an everlasting light, and thy God thy glory (Isa. 16:19).

“The kings of the earth and all the inhabitants of the world did not believe that an adversary and enemy would enter the gates of Jerusalem” (Lamentations 4:12).
“The kings of the earth and all the inhabitants of the world.” There were four kings, what this one demanded that one did not demand, and these are: David, Asa, Yehoshafat, and Hezekiah. David said: “I will pursue my enemies and overtake them…” (Psalms 18:38). The Holy One blessed be He said to him: ‘I will do so.’ That is what is written: “David smote them from twilight until the evening of their next day” (I Samuel 30:17). What is “of their next day”? Rabbi Yehoshua ben Levi said: For two nights and one day. The Holy One blessed be He would illuminate for him with comets and lightning, as we learned there: Over comets, over earthquakes, and over lightning.³⁰On any of these phenomena one recites the blessing “Whose strength and power fill the world” (Mishna Berakhot 9:2). That is what is written: “For you will illuminate my lamp…” (Psalms 18:29).
Asa arose and said: ‘I do not have the power to kill them, but I will pursue them and You do [the killing].’ He said to him: ‘I will do so,’ as it is stated: “Asa…pursued them…as they were broken before the Lord and before His camp; they carried a great many spoils” (II Chronicles 14:12). “Before Asa” is not written here, but rather, “before the Lord and before His camp.”
Yehoshafat arose and said: ‘I have the power neither to kill nor to pursue; rather, I will recite song and You do so.’ The Holy One blessed be He said to him: ‘I will do so,’ as it is stated: “At the time that they began with song and praise, [the Lord set ambushes against the children of Amon, Moav, and the highlands of Se'ir]” (II Chronicles 20:22).
Hezekiah arose and said: ‘I have the power neither to kill, nor to pursue, nor to recite song; rather I will sleep in my bed and You do so.’ The Holy One blessed be He said to him: ‘I will do so,’ as it is stated: “It was on that night that an angel of the Lord went out and smote in the camp of the Assyrians” (II Kings 19:35).
How many remained of them? Rav said: Ten, as it is stated: “A child will record them” (Isaiah 10:19), as it is typical of a child to write yod.³¹Yod is the smallest letter and its numerical value is ten. Rabbi Elazar says: Six, as it is typical of a child to scratch a line.³²The letter vav is a straight vertical line. Its numerical value is six. Rabbi Yehoshua said: Five, as it is stated: “Two, three berries at the treetop” (Isaiah 17:6).³³The two were Nebuchadnezzar and Nevuzaradan, who were officers, and the three were Sennacherib, the Assyrian king, and his two sons. They were the survivors. Rabbi Yehuda ben Rabbi Simon said: Nine. That is what is written: “Four, five on its flourishing branches” (Isaiah 17:6).³⁴Four and five are nine. Rabbi Tanḥum ben Ḥanilai said: Fourteen. That is what is written: “Two, three berries at the treetop, four, five on its flourishing branches.”
Both according to statement of these, and according to the statement of those, Nebuchadnezzar was one of them. When the Holy One blessed be He said to him: ‘Ascend and destroy the Temple,’ he said: ‘He seeks only to eliminate me. He will do to me what he did to my grandfather.’³⁵Nebuchadnezzar is identified as the grandson of Sennacherib. What did he do? He came and encamped at Daphne in Antioch and sent Nevuzaradan, captain of the guard, to destroy Jerusalem. He stayed there three and a half years. Each day he would circle Jerusalem, but was unable to conquer it. Since he was unable to conquer it, he sought to return. The Holy One blessed be He introduced [an idea] into his mind and he began measuring the wall and it was sinking two and a half handbreadths each day until it was completely sunk. Once it completely sunk, the enemies entered Jerusalem. Regarding that moment, it states: “The kings of the earth and all the inhabitants of the world did not believe that an adversary and enemy would enter the gates of Jerusalem.”

R. Chelbo again questioned R. Samuel b. Nachmeni: "It is written (Gen. 30, 25) And it came to pass, when Rachel had borne Joseph, etc. Why when Joseph was born?" And he answered: "Because Jacob our father saw that the descendants of Esau would become submissive only to the descendants of Joseph, as it is said (Oba. 1, 18) And the house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau stubble." R. Chelbo objected to him from (I. Sam. 30, 17) "And David smote them from the twilight even unto the evening of next day," etc. (Hence we see that they were submissive also to David, who was a descendant of Judah, and not of Joseph). Samuel answered: "The one who made you read the prophets did not read with thee Hagiographa, in which it is written (I Chron. 12, 21) And as he was going over to Ziklag… . captains of the thousands that belonged to Manasseh." [Hence they were submissive to the descendants of Joseph]. R. Joseph objected from (Ib. 4, 42, 43) And some of them, even of the sons of Simeon, five hundred men, went to Mount Seir, having at their head Pelatiyah and Nearyah and Rephayah, and Uzzie, the sons of Yishi. And they smote the rest of the Amalekites that had escaped, and dwelt there unto this day. Rabba b. Shila thereupon said: "Yishi was a descendant of Manasseh, as it is written (Ib. 5, 24) and the children of Manasseh were Epher and Yishi."

Zavdi ben Levi began: “The kings of the earth did not believe…” (Lamentations 4:12). There were four kings; what this one demanded that one did not demand, and they are: David, Asa, Yehoshafat, and Hezekiah. David said: “I will pursue my enemies and overtake them…” (Psalms 18:38).¹¹⁶This verse is generally translated “I have pursued my enemies” or “I pursue my enemies.” However, a more literal translation is “I will pursue my enemies” or “let me pursue my enemies,” which is how the midrash understands it here. The Holy One blessed be He said to him: ‘I will do so.’ That is what is written: “David smote them from twilight until the evening of the next day” (I Samuel 30:17). What is “of the next day”? Rabbi Yehoshua ben Levi said: For two nights and one day. The Holy One blessed be He would illuminate for him with comets and lightning, as we learned there: Over comets, over earthquakes, and over lightning.¹¹⁷Mishna Berakhot 9:2. The mishna continues: One recites: Blessed…whose strength and power fill the world. That is what is written: “For You will illuminate my lamp…” (Psalms 18:29).
Asa arose and said: ‘I do not have the power to kill them, but I will pursue them and You do [the killing].’ He said to him: ‘I will do so,’ as it is stated: “Asa…pursued them…[and Kushites were falling…before the Lord and before His camp]” (II Chronicles 14:12); it is not written here, “before Asa,” but rather, “before the Lord and before His camp.”
Yehoshafat arose and said: ‘I have the power neither to kill nor to pursue; rather, I will recite song, and You do so.’ The Holy One blessed be He said to him: ‘I will do so,’ as it is stated: “At the time that they began with song and praise, [the Lord set ambushes against the children of Amon, Moav, and the highlands of Seir]” (II Chronicles 20:22).
Hezekiah arose and said: ‘I have the power neither to kill, nor to pursue, nor to recite song; rather I will sleep in my bed and You do so.’ The Holy One blessed be He said to him: ‘I will do so,’ as it is stated: “It was on that night that an angel of the Lord went out and smote in the camp of the Assyrians [one hundred eighty-five thousand]” (II Kings 19:35).
How many remained of them? Rav said: Ten, as it is stated: “A child will record them” (Isaiah 10:19), as it is typical of a child to write a yod.¹¹⁸Yod is the smallest letter and is very easy to write. Its numerical value is ten. Rabbi Elazar says: Six, as it is typical of a child to make a line.¹¹⁹The letter vav is a straight vertical line. Its numerical value is six. Rabbi Yehoshua ben Levi said: Five, as it is stated: “Two, three berries at the treetop” (Isaiah 17:6).¹²⁰The two are Nebuchadnezzar and Nevuzaradan, who were officers, and the three were Sennacherib, the Assyrian king, and his two sons. They were the survivors (Etz Yosef). Rabbi Yehuda and Rabbi Simon said: Nine. That is what is written: “Four, five on its flourishing branches” (Isaiah 17:6).¹²¹Four and five are nine. Rabbi Tanḥum ben Ḥanilai said: Fourteen. That is what is written: “Two, three berries at the treetop, four, five on its flourishing branches” (Isaiah 17:6). Both according to the statement of these and according to the statement of those, Nebuchadnezzar was one of them. When the Holy One blessed be He said to him: ‘Ascend and destroy the Temple,’ he said: He seeks only to eliminate me. He will do to me what he did to my grandfather.¹²²The midrash identifies Nebuchadnezzar as a grandson of Sennacherib, king of Assyria during Hezekiah’s time. Alternatively, the midrash employs the term grandfather in the sense of predecessor. What did he do? He came and encamped at Daphne in Antioch and sent Nevuzaradan, captain of the guard, to destroy Jerusalem. He stayed there three and a half years. Each day he would circle Jerusalem but was unable to conquer it. He sought to return. The Holy One blessed be He introduced into his mind and he began measuring the wall, and it was sinking two and a half handbreadths each day until it was completely sunk. Once it completely sunk, the enemies entered Jerusalem. Regarding that moment, it states: “The kings of the earth and all the inhabitants of the world did not believe that an adversary and enemy would enter the gates of Jerusalem” (Lamentations 4:12). When they sinned they were exiled. When they were exiled, Jeremiah began lamenting over them, eikha.
