As Moses and the race that wandered from Egypt with him sang a
song to the Lord by the Red Sea, so shall they sing again in the
world to come. In the world to come, all generations will pass
before the Lord and will ask Him who should first intone the song
of praise, whereupon He will reply: "In the past it was the
generation of Moses that offered up to me a song of praise. Let
them do it now once more, and as Moses conducted the song by
the Red Sea, so shall he do in the world of the hereafter." [68]

In other respects, too, it shall be in the world to come as it was at
the time of the song by the sea. For when Israel intoned the song of
praise, God put on a festive robe, on which were embroidered all
the promises for a happy future to Israel. Among them were
written: "Then shall thy light break forth as the morning"; "Then
said they among the heathen. 'The Lord hath done great things for
them,'" and many similar promises. But when Israel sinned, God
rent the festive robe, and He will not restore it, or put it on until
the coming of the future world. [69]

After the men had completed the song, the women under the
guidance of Miriam sang the same song to the accompaniment of
music and dancing. The Israelites had had perfect faith, that God
would perform for them miracles and deeds of glory, hence they
had provided themselves with timbrels and with flutes, that they
might have them at hand to glorify the anticipated miracles. [70]
Then Miriam said to the women, "Let us sing unto the Lord, for
strength and sublimity are His; He lords it over the lordly, and He
resents presumption. He hurled Pharaoh's horses and chariots into
the sea, and drowned them, because wicked Pharaoh in his
presumption pursued God's people, Israel." [71]
