'Sake' in the Bible

Yet the LORD would not destroy Judah for David his servant's sake, as he promised him to give him alway a light, and to his children.

and Jehovah doth favour them, and pity them, and turn unto them, for the sake of His covenant with Abraham, Isaac, and Jacob, and hath not been willing to destroy them, nor to cast them from His presence as yet.

For I will defend this city, to save it, for mine own sake, and for my servant David's sake.

And I will add unto thy days fifteen years; and I will deliver thee and this city out of the hand of the king of Assyria; and I will defend this city for mine own sake, and for my servant David's sake.
