John Calvin's Bible Commentary
Jeremiah 51:38
Here, by another figure, Jeremiah expresses what he had said of the destruction of Babylon, even that in the middle of the slaughter, they would have no strength to resist: they would, at the same time, perish amidst great confusion; and thus he anticipates what might have been advanced against his prophecy. For the Babylonians had been superior to all other nations; how then could it be, that a power so invincible should perish? Though they were as lions, says the Prophet, yet that would avail nothing; they will indeed roar, but roaring will be of no service to them; they will roar as the whelps of lions, but still they will perish.
We now, then, understand the object of this comparison, even that the superior power by which the Babylonians had terrified all men would avail them nothing, for nothing would remain for them in their calamity except roaring. (100) It follows, —
Together as young lions shall they roar. And rouse themselves as whelps of lionesses.
There is a ו wanting before the last verb, which is supplied by the Vulg. , Syr. , and the Targ. ; and it is rendered necessary by the tense of the verb. — Ed
