“Circumcise yourselves to the LORD, 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 that none can quench it, because of the evil of your doings.”
King James Version (KJV)
Matthew Henry's Concise Commentary
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.
“He that giveth unto the poor shall not lack: but he that hideth his eyes shall have many a curse.”
