'Leave' in the Bible

while you leave to God's judgement those who are outside? Remove the wicked man from among you.

But to those already married my instructions are--yet not mine, but the Lord's--that a wife is not to leave her husband;

If, however, the unbeliever is determined to leave, let him or her do so. Under such circumstances the Christian man or woman is no slave; God has called us to live lives of peace.
