41 If thou wilt return, O Israel, saith Jehovah, return unto me; and if thou wilt put away thine abominations out of my sight, then shalt thou not be a wanderer; 2 —and thou shalt in truth, in justice, and in righteousness swear, [As] Jehovah liveth! and the nations shall bless themselves in him, and in him shall they glory.

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 4:1-4

Commentary on Jeremiah 4:1-2

(Read Jeremiah 4:1-2)

The first two verses should be read with the last chapter. Sin must be put away out of the heart, else it is not put away out of God's sight, for the heart is open before him.

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.
