'For Us' in the Bible

Then all the men of Judah answered the men of Israel, “Because the king is a close relative to us. Why then are you angry about this matter? Have we eaten at all at the king’s expense, or has anything been taken for us?”

Then the Gibeonites said to him, “We have no concern of silver or gold with Saul or his house, nor is it for us to put any man to death in Israel.” And he said, “I will do for you whatever you say.”
