'Justify' in the Bible

Keep your distance from a false charge -- do not kill the innocent and the righteous, for I will not justify the wicked.

If you have any words, reply to me; speak, for I want to justify you.

So now, bear your disgrace, because you have given your sisters reason to justify their behavior. Because the sins you have committed were more abominable than those of your sisters; they have become more righteous than you. So now, be ashamed and bear the disgrace of making your sisters appear righteous.
