2 Samuel (Author Compiled by Isaiah from records of Samuel, David, Nathan, and Gad.)
8:2And he smote Moab, and measured them with a line, casting them down to the ground; even with two lines measured he to put to death, and with one full line to keep alive. And so the Moabites became David's servants, and brought gifts.
