Midrash su Salmi 69:3

(Exodus, Ibid. 3) "The L rd is a man of war; the L rd is His name." R. Yehudah says: This is a verse rich from (what is written) in many places. We are hereby apprised that He revealed Himself to them in the implements of war. He revealed Himself to them as a warrior girded with a sword, viz. (Psalms 45:4) "Gird Your sword upon Your thigh, O Hero. He revealed Himself to them as a rider, viz. (Ibid. 18:11) "And He mounted a cherub and flew, etc." He revealed Himself to them in mail and helmet, viz. (Isaiah 59:17) "He donned righteousness as mail, and a helmet of salvation on His head." He revealed Himself to them with a spear, viz. (Habakkuk 3:11) "by the light of the flash of Your spear," and (Psalms 35:3) "and draw spear and (don) buckler, etc." He revealed Himself to them with bow and arrows, viz. (Habakkuk 3:9) "The nakedness of Your bow will be revealed," and (II Samuel 22:15) "And He sent forth arrows, etc." He revealed Himself to them with shield and buckler, viz. (Psalms 91:4) "Shield and bucker is His Your truth, and (Ibid. 35:2) "Take up buckler and shield." I might think that He (actually) required one of all these appurtenances. It is, therefore, written "The L rd is a man of war; the L rd is His name. It is with His name that He wars, and not with any of these appurtenances. Why, then, need each of them be singled out? For if Israel requires it, He makes war for them. And woe to the nations what they hear with their ears, that He who spoke and brought the world into being is destined to make war with them! "the L rd is a man of war': What is the intent of this? Because He revealed Himself at the sea as a hero waging war — "The L rd is a man of war" — and He revealed Himself at Sinai as an elder full of mercy, viz. (Exodus 24:10) "And they saw the G d of Israel … and under His feet as the work of a sapphire brick and as the appearance of the heavens in brightness" [[ see Rashi], and (Daniel 7:9) "I watched as thrones were set up, and the Ancient of Days sat … (10) A stream of fire was flowing forth from before Him, etc." — So as not to give a pretext to the peoples of the world to say that there are two (i.e., numerous) deities, (it is written) "The L rd is a man of war — the L rd is His name. It was He upon the sea, He in Egypt, He in the past, He in the future, He in time to come, He in this world, He in the world to come. As it is written (Devarim 32:39) "See, now, that it is I, I, and there is no god with Me, etc.", and (Isaiah 41:4) "Who wrought and did? The Caller of the generations (into being) from the beginning. I, the L rd, was the first (to perform wonders and to help,) and it is I (who will be) with (you,) the later (generations." There is a warrior in a province, accoutered in all the weapons of war, but lacking power, strength, stratagem, and war (wisdom). Not so, the Holy One Blessed be He. He possesses all of these. As it is written (I Samuel 17:42) "For unto the L rd is the war, and He will deliver you into our hands." And it is written (Psalms 144:1) ("A psalm) of David: Blessed is the L rd, my Rock, who trains my hands for battle, my fingers for war." There is a warrior, at the height of his power, forty years old, who is not like a sixty-year-old, nor a sixty-year-old like a seventy-year-old, but the older he grows the more his power wanes. Not so, He who spoke and brought the world into being — (Malachi 3:6) "I am the L rd. I have not changed! There is a warrior in a province, who may be so swayed by wrath and power s to vent his fury even upon his father and mother and close of kin. Not so, the Holy One Blessed be He. "The L rd is a man of war — the L rd ("yod-keh-vav-keh," signifying mercy) is His name. "The L rd is a man of war" — who fought against the Egyptians. "The L rd is His name — He compassionates His creations, viz. (Exodus 24:6) "The L rd, the L rd, the G d (Kel) who is merciful and gracious, etc." There is a warrior in a province. As soon as the arrow leaves his hand he cannot retrieve it. Not so, the Holy One Blessed be He. When Israel do not do His will, a decree goes forth from Him, viz. (Devarim 32:41) "When I whet the flash of My sword, etc." But if they repent, immediately he withdraws it, viz. (Ibid.) "My hand shall take hold of justice." I might think that He withdraws it in vain (i.e., unbloodied); it is, therefore, written (Ibid.) "I shall return (with that sword) vengeance to My adversaries." Against whom does He return it? The nations of the world, viz. (Ibid.) "and (with it) My haters shall I repay!" A king of flesh and blood goes out to war and (emissaries of) neighboring lands come and request sustenance form him. He tells them angrily that he is going to war. When he returns victorious, they come and request sustenance form him. "The L rd is a man of war" — He wars against Egypt. "the L rd is His name" — (At the same time) He hears the outcries of all who enter the world. As it is written (Psalms 65:3) "Heeder of prayer — to You does all flesh come. A king of flesh and blood, whilst at war, cannot supply all of his soldiers. Not so, the Holy One Blessed be He. "The L rd is a man of war" — He wars against Egypt. "The L rd is His name" — He sustains all who enter the world. As it is written (Psalms 136:13) "He divides the sea into strips" (twelve strips for twelve tribes) — (Ibid. 25) "He gives bread to all flesh." (Ibid. 147:10) He gives the beast its food, the raven's young, what they call for." "The L rd is a man of war": Is it possible to say this (i.e., to refer to Him as "a man")? Is it not written (of His transcendent majesty) (Jeremiah 23:24) "Do I not fill heaven and earth, sys the L rd"? And (Isaiah 6:3) "And one (seraph) would call to another and say: Holy, Holy, Holy, etc." And (II Chronicles 6:14) "O L rd, G d of Israel, there is none like You, etc." And (Ezekiel 43:2) "And, behold, the glory of the G d of Israel, etc." What, then, is the intent of "a man of war"? Because of your love (i.e., the love He has for you) and because of your holiness, I shall sanctify My name through you. For it is written (Hoshea 11:9) "For I am G d, and not a man, etc." "the L rd is His name": It is with His name that He wars, and He has no need of any of these (military) appurtenances. And thus did David say (I Samuel 17:95) "You come to me with sword, and spear, and javelin; but I come to you with the name of the L rd of hosts, etc." And (Psalms 20:8) "These with chariots and these with horse, but we with the name of the L rd our G d, etc." And thus did Assa say, viz. (II Chronicles 14:10) "And Assa called out to the L rd his G d and said: O L rd, there is none besides You, etc." (Exodus 15:4) "the chariots of Pharaoh and his host": "As one measures, so is it meted out to him." They (the Egyptians [i.e., Pharaoh]) said (Ibid. 5:2) "Who is the L rd that I should hearken to his voice?" And You meted it out to him accordingly, viz. "The chariots of Pharaoh, etc." One verse (here) states "yarah" (He cast into the sea"), and, another (Ibid. 1) "ramah" ("He lifted into the sea"). How are these two verses to be reconciled? "Yarah" — they descended to the depths; "ramah" — they rose to the heights. Variantly: "The chariots of Pharaoh, etc." They (the Egyptians [i.e., Pharaoh') said (Ibid. 1:22) "Every son that is born into the Nile shall you thrown him, You, likewise, meted it out to him accordingly, viz.: "The chariots of Pharaoh, etc." They (Ibid. 14:7): "And he took six hundred chosen chariots." You, likewise (Ibid. 15:4): "and the élite of his officers were mired in the sea. They placed (Ibid. 14:7) "officers upon all of them"; You, likewise, (Ibid. 17:5) [He mired them there] "so that the waters should [return and] cover them." They (Ibid. 1:14) "embittered their lives with hard toil, with mortar"; You, likewise, made the water like slime for them, and they sank in it. Thus (15:4) "They were mired in the Red Sea," "mired" connoting slime, as in (Psalms 69:3) "I am sunk in the slime of the depths," and (Jeremiah 38:6) "and Jeremiah sank in the slime." Thus, "they were mired in the sea."

... Teach us oh, teacher: once the Ninth of Av has ended, is everything permitted? R’ Chiyah the Great taught like this: once the Ninth of Av has ended, one is permitted to do anything. Why? Because it is like the case of a person whose dead is laid out before him, who is forbidden to eat meat or drink wine. Once the dead is buried, the mourner is permitted to do so. So to on the Ninth of Av one is a mourner – once the day has ended one is permitted to do anything. Even though we are permitted, we must always have a sigh in our hearts until the Holy One returns to her. The Holy One said to them: by your lives! I burnt her, as it says “From above He has hurled fire into my bones…” (Lamentations 1:13) I will build her, as it says “Yet again will I rebuild you, then you shall be built, O virgin of Israel…” (Jeremiah 31:3) Zion said to Him: Behold, I have been sitting thus for many years! I have counted the days from old and I have not been redeemed, therefore I have despaired. She said that my master has abandoned me. And from where do we learn that Zion said this? From that which is written regarding it “And Zion said, ‘The Lord has forsaken me, and the Lord has forgotten me.’” (Isaiah 49:14) ... Another explanation. “And Zion said, ‘The Lord has forsaken me…” (Isaiah 49:14) What is written before this? “Sing, O heavens, and rejoice, O earth, and mountains burst out in song, for the Lord has consoled His people, and He shall have mercy on His poor.” (Isaiah 49:13) Once Zion saw that the prophet recalled His people and His poor, but did not mention Zion or Jerusalem she said ‘the Lord has forsaken me, and the Lord has forgotten me.’ Immediately the Holy One replied and said to her: just as it is impossible for a woman to forget her sucking child, so to I am not able to forget you, “Shall a woman forget her sucking child, from having mercy on the child of her womb?” (Isaiah 49:15) She said to Him: Master of the world! How is that possible? There is no end to the evils I have done! I caused Your Holy Temple to be destroyed and I killed the prophets. R’ Berachia the Kohen said in the name of Rebbe: the Holy One said to her, I will forget your evil but I will not forget your good. “…These too shall forget, but I will not forget you.” (ibid.) I have forgotten “"These are your gods, O Israel…” (Exodus32:4) but “I am the Lord, your God…” (Exodus 20:2) I will not forget.
