II Samuel 8:2

2 David also defeated the Moabites. He made them lie down on the ground and measured them off with a length of cord. Every two lengths of them were put to death, and the third length was allowed to live. So the Moabites became subject to David and brought him tribute.

2 Também derrotou os moabitas; fê-los deitar em terra e os mediu: duas vezes um cordel, para os matar; uma vez um cordel, para os deixar com vida. Assim, ficaram os moabitas por servos de Davi e lhe pagavam tributo.
