And he said, If the Syrians shall be too strong for me, then thou shalt help me: but if the children of Ammon shall be too strong for thee, then I will come and help thee.
And when the children of Ammon saw that the Syrians had fled, then fled they also before Abishai, and entered into the city. So Joab returned from the children of Ammon, and came to Jerusalem.
And he smote Moab, and measured them with a line, casting them down to the ground; even with two lines he measured to put to death, and with one full line to keep alive. And so the Moabites became David's servants, and brought gifts.
Them also king David dedicated to the LORD, with the silver and the gold that he brought from all these nations; from Edom, and from Moab, and from the children of Ammon, and from the Philistines, and from Amalek.
And David and his men went up, and invaded the Geshurites, and the Gezrites, and the Amalekites: for those nations were of old the inhabitants of the land, as thou goest to Shur, even to the land of Egypt.
And David smote them from the twilight even to the evening of the next day: and there escaped not a man of them, save four hundred young men, who rode upon camels, and fled.
