3 For this is what the Lord says to the men of Judah and to Jerusalem: Get your unworked land ploughed up, do not put in your seeds among thorns. 4 Undergo a circumcision of the heart, you men of Judah and people of Jerusalem: or my wrath may come out like fire, burning so that no one is able to put it out, 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.
