The Work of My Hands is Drowning in the Sea: The Drowned or the Saved? Rabbi Adam Mintz Shabbat Hagadol 2016

(42) "At the fall of your enemies do not rejoice": And so too does God command "When you see the donkey of your hater; when you encounter the donkey of your enemy." God says; Are you not better than I? How is this so? The Jews were worthy to recite [full] Hallel all seven days of Pesach as they recite it on the seven days of Succot. Why is the [full] Hallel recited only on the first day of Pesach? Rather, since the Egyptians died and were drowned in the sea and they are My enemies and I wrote "At the fall of your enemies do not rejoice". So too do you find with Noah for whom marital relations were forbidden in the ark.

What is meant by, And one approached not the other all night? In that hour the ministering angels wished to utter the song [of praise] before the Holy One, blessed be He, but He rebuked them, saying: My handiwork [the Egyptians] is drowning in the sea; would ye utter song before me?

(7) Another explanation: "Then Moshe sang" - Rabbi Yochanan said, "The angels requested to recite song in front of the Holy One, blessed be He, on that night that the Jews crossed the sea; and the Holy One, blessed be He, did not allow them. He said to them, 'My legions are in dire straits and you are reciting song in front of Me?' This is [the understanding] of that which is written (Exodus 14:20), 'and they did not come close, each to one another the whole night' - as you say [with reference to the angels (Isaiah 6:3)], 'and they called (here understood as greeted) each to one another' (every other night).

...And what is the meaning of 'and all faces are turned into paleness?' — R. Johanan said: [This refers to God's] heavenly family [I.e., the angels] and his earthly family [I.e., Israel,] when God says, These [the Gentiles] are my handiwork, and so are these [the Jews]; how shall I destroy the former on account of the latter?
