(17) Now when Pharaoh let the people go, God did not lead them by way of the land of the Philistines, although it was nearer; for God said, “The people may have a change of heart when they see war, and return to Egypt.” (18) So God led the people round about, by way of the wilderness at the Sea of Reeds.
Now the Israelites went up armed out of the land of Egypt.

(1) Then Moses and the Israelites sang this song to GOD. They said:
I will sing to GOD, who has triumphed gloriously;Horse and driver have been hurled into the sea.

(19) For the horses of Pharaoh, with his chariots and riders, went into the sea; and GOD turned back on them the waters of the sea; but the Israelites marched on dry ground in the midst of the sea.

(17)If your enemies fall, do not exult;If they trip, let your heart not rejoice,

(3) Another interpretation (of Exod. 15:1): THEN SANG. When Israel was camping by the sea, the ministering angels came to praise the Holy One, but the Holy One did not give them permission, as stated (in Exod. 14:20): AND THE ONE DID NOT COME NEAR THE OTHER…. It also says (in Is. 6:3): AND ONE CRIED UNTO THE OTHER. To whom are they comparable? To a king whose son was taken prisoner. He clothed himself in vindictiveness against his enemies. When he went to bring him , the people came to utter a hymn for him. He said to them: When I have redeemed my son, you will praise me. Similarly Israel was put in distress by the sea. The ministering angels came to praise him. He rebuked them. The Holy One said to them: When my children are put in distress, would you offer me praise? When they came up from the sea, Israel and the ministering angels wanted to utter a song. R. Abbin the Levite said: To what is the matter comparable? To a king who went down to battle and won. His son and his servant came to him, and in their hands was a crown to put on the king's head. They came to the king and said to him: Your son and your servant are standing by with a crown in their hands. Who will enter first? He said to them: the world's greatest fools! Shall my servant precede my son? Let my son enter first. Similarly, when Israel came up from the sea, Israel and the ministering angels came to utter a song. The Holy One said to the ministering angels: Let Israel be first. (Exod. 15:1:) THEN SANG MOSES [AND THE CHILDREN OF ISRAEL]. The women and the ministering angels were found to be standing by. Who would offer praise first? R. Hiyya bar Abba bar Shallum said: He made peace between them, as stated (in Ps. 68:26 [25]): SINGERS COME FIRST; THEN FOLLOW MUSICIANS IN THE MIDST OF TIMBREL-PLAYING MAIDENS. (Ibid.:) THE SINGERS COME FIRST {THEN FOLLOW MUSICIANS}. These are Israel. {AND AFTERWARDS} [THEN FOLLOW] MUSICIANS. These are the angels. {And afterwards} IN THE MIDST OF TIMBREL-PLAYING MAIDENS. [These are the women.] R. Levi said: By the heavens, I do not accept this interpretation. Rather the women first offered praise, simply because THEN FOLLOW THE MUSICIANS. These are Israel. IN THE MIDST OF TIMBREL-PLAYING MAIDENS. These are the women. The ministering angels began to complain to the Holy One. They said: Is it not enough for the men to precede us? But are the women to do so as well? The Holy One said to them: As you live, yes. R. Helbo said in the name of R. Samuel bar Nahman: See what is written (in Ezek. 3:12): THEN THE SPIRIT RAISED ME UP, AND AFTER MEI HEARD A SOUND. What is the meaning of AFTER ME ('HRY)? After ('HRY) I and my friends have offered praise. Then afterwards the ministering angels went and said (ibid., cont.): BLESSED IS THE GLORY OF THE LORD FROM HIS PLACE. R. Pinhas ben Hama the Priest said: What is written (in Ezek. 1:24)? WHEN THEY STOOD, THEY WOULD LET THEIR WINGS DROOP. What is the meaning of [WHEN THEY STOOD]? Whoever hears WHEN THEY STOOD is thinking: Perhaps there is sitting above. [Heaven forbid. There is no sitting above.] Rather they all stand, as stated (in Is. 6:2): THE SERAPHIM STOOD…. And so it says (in Dan. 7:16): I DREW NEAR TO ONE OF THOSE STANDING THERE. What is the meaning of WHEN THEY STOOD? Simply that when Israel stands and praises the Holy One, at that time THEY LET THEIR WINGS DROOP.

(Exodus 14:21) "and He made the sea into dry land and the waters were split." All the waters in the world were thus rendered.
