Charles Ellicott Commentary Jeremiah 30:23-24

"Behold, the tempest of Jehovah, [even his] wrath, is gone forth, a sweeping tempest: it shall burst upon the head of the wicked. The fierce anger of Jehovah shall not return, until he have executed, and till he have performed the intents of his heart: in the latter days ye shall understand it." — Jeremiah 30:23-24 (ASV)

Behold, the whirlwind of the Lord ... —The “wicked” who are thus threatened are the enemies and oppressors of the penitent and rescued people. In the “latter days,” the far-off future (Genesis 49:1; Numbers 24:14; Isaiah 2:2), it would be seen that He was their avenger. (See Notes on Jeremiah 23:19-20.) A right division of chapters would probably connect this with the great promise of Jeremiah 31:1.
