2 Samuel 21:2

21:2 So the king summoned the Gibeonites and spoke with them. (Now the Gibeonites were not descendants of Israel; they were a remnant of the Amorites. The Israelites had made a promise to them, but Saul tried to kill them because of his zeal for the people of Israel and Judah.)

Ezekiel 17:18-19

17:19 “‘Therefore this is what the sovereign Lord says: As surely as I live, I will certainly repay him for despising my oath and breaking my covenant!
