Midrash su Abacuc 3:9

(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."

“Behold the bed of Solomon: sixty valiant men surround it, from the valiant of Israel, each armed with a sword, trained in war; each man, a sword on his thigh, from fear in the nights” (Song of Songs 3:7–8).
“Behold the bed of Solomon: sixty valiant men surround it,” Rabbi Beivai in the name of Rabbi Elazar ben Rabbi Yosei interpreted the verse regarding the Priestly Benediction. “Behold the bed [mitato],” behold his tribes [matotav] and his clans, just as it says: “The oaths to the tribes [matot]” (Habakkuk 3:9); “of Solomon [Shlomo],” of the king [of Whom it may be said that] peace [shalom] is His; “sixty valiant men surround it,” these are the sixty letters in the Priestly Benediction; “from the valiant of Israel,” as they bolster Israel.
“Each armed with a sword,” Rabbi Azarya said: Matters that are blessed with Might,⁸¹Each blessing contains the name of the mighty God. “may the Lord bless you” (Numbers 6:24), “may the Lord shine” (Numbers 6:25), “may the Lord lift” (Numbers 6:26). “Trained in war,” as they battle all sorts of calamities that exist in the world. “Each man, a sword on his thigh from fear in the nights,” for even if a person sees in his dream a sword cutting his thigh, what shall he do? He shall go to the synagogue, recite Shema, pray his prayer, hear the Priestly Benediction, and answer amen after them, and no evil matter will harm him. Therefore, He cautions the sons of Aaron and says to them: “So you shall bless the children of Israel” (Numbers 6:23).

The Rabbis interpreted the verse regarding those who departed from Egypt. “Behold the bed [mitato],” his tribes [matotav] and his clans, just as it says: “The oaths of the tribes [matot]” (Habakkuk 3:9); “of Solomon [Shlomo],” of the king [of Whom it may be said] that peace [shalom] is His; “sixty valiant men,” these are the six hundred thousand who departed Egypt from twenty years of age and above; “from the valiant of Israel,” these are the six hundred thousand who departed Egypt from twenty years of age and below.
“Each armed with a sword, trained in war; each man, a sword on his thigh,” for when Moses said: ‘The Holy One blessed be He told me the following principle: “All uncircumcised shall not eat from it”’ (Exodus 12:48); immediately, each and every one took his sword on his thigh and circumcised himself.
Who circumcised them? Rabbi Berekhya said: Moses was the circumciser, Aaron uncovered the skin,⁸⁹After the foreskin is severed, one pulls back a thin membrane under it and uncovers the corona. and Joshua gave them to drink. Some say: Joshua was the circumciser, Aaron uncovered the skin, and Moses gave them to drink; that is what is written: “At that time, the Lord said to Joshua: Make flint knives for yourself and circumcise the children of Israel again, a second time” (Joshua 5:2). Why “a second time”? From here [it may be derived] that he circumcised them the first time. Immediately, “Joshua made flint knives for himself, and circumcised the children of Israel at the Hill of the Foreskins” (Joshua 5:3). What is “at the Hill of the Foreskins”? Rabbi Levi said: From here [it may be derived] that they made that hill out of foreskins.
