3 For thus saith Jehovah to the men of Judah and Jerusalem: Break up for you a fallow ground, and sow not among thorns. 4 Circumcise yourselves for Jehovah, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem; lest my fury come forth like fire and burn, and there be none to quench it, because of the evil of your doings.

Matthew Henry's Commentary on Jeremiah 4:3-4

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.
