'Sake' in the Bible

However Yahweh would not destroy Judah, for David his servant's sake, as he promised him to give to him a lamp for his children always.

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

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