Jeremiah 10:18 - Matthew Poole's English Annotations on the Holy Bible

I will sling out; it notes with how much violence, and speed, and with ease the Chaldeans shall hurry away the people into Babylon, as the stone doth swiftly and violently pass which is thrown out of a sling, with so much ease, and therefore it is said at at this once; I will not delay, but make one thorough quick work of it; noting not only the time, but implying the clear riddance the he would make of them, 2 Chronicles 36:17-19: they had been often assaulted by enemies, and sometimes they redeemed themselves, sometimes delivered by God, their enemies being sometimes divided; but it should not be so now, but all swept away. That they may find it so; that they may see I am in good earnest, that I have not only said it, but they shall find that I will execute it; and though they would never believe it, yet they shall actually find the truth of my threatenings. See Jeremiah 5:12,13 Eze 6:10.
