2 Samuel 8:1-2

11Now after this it came about that David 2defeated the Philistines and subdued them; and David took 3control of the chief city from the hand of the Philistines.

24He 5defeated 6Moab, and measured them with the line, making them lie down on the ground; and he measured two lines to put to death and one full line to keep alive. And 7the Moabites became servants to David, 8bringing tribute.
