Ia juga mengalahkan orang Moab, lalu mengukur mereka dengan tali, sambil menyuruh mereka berbaring di tanah; ia mengukur dua tali untuk dibunuh dan satu tali penuh untuk dibiarkan hidup. Maka orang Moab menjadi hamba Daud, yang membawa upeti.
Rashi
Those measured with two ropes were killed. [This vengeance was] because they killed his father, his mother and his brothers as it is said, "He led them before the king of Moav." (Shmuel I, 22:4) We do not find that they ever left from there.4Yalkut Shimoni, 147.
