(Jer 3:11 KJV) And the LORD said unto me, The backsliding Israel hath justified herself more than treacherous Judah.
 

(Jer 4:4 KJV) 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.
