'Leave' in the Bible

not at all meaning the people of this world who are immoral, greedy, robbers, or idolaters. In that case you would have to leave this world.

To married people I give this command (not really I, but the Lord): A wife must not leave her husband.

But if she does leave him, she must remain unmarried or else be reconciled to her husband. Likewise, a husband must not abandon his wife.
