The Targum Pseudo-Jonathan on Exodus 14:24 picks a very specific moment for the Egyptian catastrophe. It happened in the morning watch—and the Targum tells us why that hour matters. It is the time when the powers on high come to offer praise. Dawn is when the angels sing.
Into that chorus, God looks down at the Mizraee with anger. The Targum gives Him weapons drawn from the two columns that have been escorting Israel all along. From the column of fire He hurls "flakes of fire and hail." From the column of cloud He "confounded the host of the Mizraee."
Notice the combination: fire and hail. It is the seventh plague (Exodus 9:23-24) replayed on the battlefield. The same two elements that destroyed Egyptian agriculture now destroy the Egyptian army. The Targum is insisting that the destruction at the sea is the tenth plague's continuation.
And the timing—the morning watch, the hour of angelic praise—is not neutral. The Targum is drawing on a tradition (later expressed in Megillah 10b) that when God is about to execute judgment, the angels want to sing. God silences them when the dying are Egyptians, saying "the works of My hands are drowning in the sea, and you want to sing?" The Targum here gives us the pre-silencing moment: the chorus begins, and into that music God delivers the verdict.
Takeaway: the Targum teaches that even God's anger is scheduled with care, and that the hour of judgment is also the hour of heavenly song.
