John Gill Commentary Jeremiah 4:13

"Behold, he shall come up as clouds, and his chariots [shall be] as the whirlwind: his horses are swifter than eagles. Woe unto us! for we are ruined." — Jeremiah 4:13 (ASV)

Behold, he shall come up as clouds Meaning the lion, Nebuchadnezzar, (Jeremiah 4:7), the king with his army (as the Targum paraphrases it); he shall come up against them as a cloud that ascends and covers the earth. The metaphor denotes the swiftness of his coming, and the multitudes he should come with, and that darkness and distress he should bring with him upon the people of the Jews:

and his chariots shall be as a whirlwind; for swiftness, power, and violence: chariots for war are intended; see (Isaiah 5:28):

his horses are swifter than eagles: the swiftest of birds. The same thing is designed as by the other metaphors; the swiftness and suddenness of the Jews' destruction:

woe unto us, for we are spoiled; their destruction was inevitable, there was no escaping it; and therefore their case was woeful and miserable.
