41 If you will come back, O Israel, says the Lord, you will come back to me: and if you will put away your disgusting ways, you will not be sent away from before me. 2 And you will take your oath, By the living Lord, in good faith and wisdom and righteousness; and the nations will make use of you as a blessing, and in you will they take a pride.
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 4:1-4
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.
