'Justified' in the Bible

Neither hath Samaria committed half of thy sins; but thou hast multiplied thine abominations more than they, and hast justified thy sisters in all thine abominations which thou hast done.

Thou also, which hast judged thy sisters, bear thine own shame for thy sins that thou hast committed more abominable than they: they are more righteous than thou: yea, be thou confounded also, and bear thy shame, in that thou hast justified thy sisters.
