12 O family of David, this is what the Lord has said: Do what is right in the morning, and make free from the hands of the cruel one him whose goods have been violently taken away, or my wrath will go out like fire, burning so that no one may put it out, because of the evil of your doings.
Matthew Henry's Commentary on Jeremiah 21:12
Commentary on Jeremiah 21:11-14
(Read Jeremiah 21:11-14)
The wickedness of the king and his family was the worse because of their relation to David. They were urged to act with justice, at once, lest the Lord's anger should be unquenchable. If God be for us, who can be against us? But if he be against us, who can do any thing for us?
