2. Samuel 8:2

Subjugation of Moab. - "He smote Moab (i.e., the Moabites), and measured them with the line, making them lie down upon the ground, and measured two lines (i.e., two parts) to put to death, and one line full to keep alive." Nothing further is known about either the occasion or the history of this war, with the exception of the cursory notice in Ch1 11:22, that Benaiah, one of David's heroes, smote two sons of the king of Moab, which no doubt took place in the same war. In the earliest period of his flight from Saul, David had met with a hospitable reception from the king of Moab, and had even taken his parents to him for safety (Sa1 22:3-4). But the Moabites must have very grievously oppressed the Israelites afterwards, that David should have inflicted a severer punishment upon them after their defeat, than upon any other of the nations that he conquered, with the exception of the Ammonites (Sa2 12:31), upon whom he took vengeance for having most shamefully insulted his ambassadors (Sa2 10:2.). The punishment inflicted, however, was of course restricted to the fighting men who had been taken prisoners by the Israelites. They were ordered to lie down in a row upon the earth; and then the row was measured for the purpose of putting two-thirds to death, and leaving one-third alive. The Moabites were then made "servants" to David (i.e., they became his subjects), "bringing gifts" (i.e., paying tribute).

David having sought first the kingdom of God and the righteousness thereof, settling the ark as soon as he was himself well settled, we are here told how all other things were added to him. Here is an account, I. Of his conquests. He triumphed, 1. Over the Philistines (Sa2 8:1). 2. Over the Moabites (Sa2 8:2). 3. Over the king of Zobah (Sa2 8:3, Sa2 8:4). 4. Over the Syrians (Sa2 8:5-8, Sa2 8:13). 5. Over the Edomites (Sa2 8:14). II. Of the presents that were brought him and the wealth he got from the nations he subdued, which he dedicated to God (Sa2 8:9-12). III. Of his court, the administration of his government (Sa2 8:15), and his chief officers (Sa2 8:16-18). This gives us a general idea of the prosperity of David's reign.

8:2 Moab was on the east side of the Dead Sea. Earlier, the people of Moab had provided David’s parents with refuge during Saul’s reign (1 Sam 22:3-4); David’s great-grandmother, Ruth, was from Moab. For whatever reason, no such fraternal relationship existed any longer. • two groups to be executed for every one group to be spared: This is the only time in 2 Samuel that David executed captives taken in battle (see Num 21:29; 24:17; Deut 2:9).
