When the Egyptians were drowning in the Red Sea, the angels in heaven began to break forth in songs of jubilation, but the Holy One, blessed be He, silenced them: “My creatures are perishing — and ye are ready to sing!”

בִּקְּשׁוּ מַלְאֲכֵי הַשָּׁרֵת לוֹמַר שִׁירָה, אָמַר הַקָּדוֹשׁ בָּרוּךְ הוּא: מַעֲשֵׂה יָדַי טוֹבְעִין בַּיָּם, וְאַתֶּם אוֹמְרִים שִׁירָה

A comment from Rabbi Johanan (d. AD 179), discussing the question whether God rejoices in the downfall of the wicked, referencing the destruction of the pursuing Egyptian army at the Red Sea (Exodus 14:21-31). Some sources suggest the song to be sung was Isaiah 6:3.

In addition to Megillah 10b, this passage is echoed in Seder Nezikin, Sanhedrin 39b.5:

בְּאוֹתָהּ שָׁעָה בִּקְּשׁוּ מַלְאֲכֵי הַשָּׁרֵת לוֹמַר שִׁירָה לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא. אָמַר לָהֶן הַקָּדוֹשׁ בָּרוּךְ הוּא: מַעֲשֵׂה יָדַי טוֹבְעִין בַּיָּם וְאַתֶּם אוֹמְרִים שִׁירָה לְפָנַי
