3 For thus says the Lord to the people of Judah and to the inhabitants of Jerusalem: Break up your fallow ground, and do not sow among thorns. 4 Circumcise yourselves to the Lord, remove the foreskin of your hearts, O people of Judah and inhabitants of Jerusalem, or else my wrath will go forth like fire, and burn with no one 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.
