But also you shall not cut off your kindness from my house forever--no, not even when the Lord has cut off every enemy of David from the face of the earth. (AMP)
But also thou shalt not cut off thy kindness from my house for ever: no, not when the LORD hath cut off the enemies of David every one from the face of the earth. (KJV)
