1 Chronicles 18:13

And he put garrisons (or “prefects,” 1 Chronicles 18:6) in Edom. — Samuel adds, “in all Edom he set garrisons,” thus marking the complete subjugation of the country.

Thus the Lord preserved David. — See 1 Chronicles 18:6. David was victorious on all sides, north (1 Chronicles 18:3), and south, and east, and west (1 Chronicles 18:11). The six peoples whom he reduced had been the foes of his ill-fated predecessor (1 Samuel 14:47).
