2 Samuel 8:1-2

Young's Literal Translation

8 And it cometh to pass afterwards that David smiteth the Philistines, and humbleth them, and David taketh the bridle of the metropolis out of the hand of the Philistines.

² And he smiteth Moab, and measureth them with a line, causing them to lie down on the earth, and he measureth two lines to put to death, and the fulness of the line to keep alive, and the Moabites are to David for servants, bearers of a present.
