4 Circumcise yourselves to the Lord, circumcise your hearts, you people of Judah and inhabitants of Jerusalem, or my wrath will flare up and burn like fire because of the evil you have done- burn with no one to quench it.

Matthew Henry's Commentary on Jeremiah 4:4

Commentary on Jeremiah 4:3-4

(Read Jeremiah 4:3-4)

An unhumbled heart is like ground untilled. It is ground which may be improved; it is our ground let out to us; but it is fallow; it is over-grown with thorns and weeds, the natural product of the corrupt heart. Let us entreat the Lord to create in us a clean heart, and to renew a right spirit within us; for except a man be born again, he cannot enter into the kingdom of heaven.
