'Sake' in the Bible

Yet Yahweh was not willing to destroy Judah, for the sake of David his servant, as he had promised to give him a lamp for his sons always.

And I will defend this city to save her for my sake and for the sake of David my servant.'"

I will add to your days fifteen years, and from the hand of the king of Assyria I will deliver you and this city. I will defend this city for my sake and for the sake of David my servant." '"
