1 Samuel 30:17-26
17 And David laid upon them from the twilight until the evening on the morrow: so that there escaped not a man, save four hundred young men which rode away upon camels and fled.
18 And David recovered all the Amalekites had carried away, and his two wives:
19 so that there was no person lacking, small or great, son or daughter, or of the spoil of all that they had taken away — David brought all again.
20 And David took all the sheep, and the oxen. And they drave the cattle before, and said, "This is David's prey."
21 And then David came to the two hundred men that were too weary for to follow David which they made to abide at the river Besor. And they came to meet David and the people that were with him. And when David came to the people, he saluted them.
22 Then answered all the wicked and the unthrifty of the men that went with David, and said, "Because they went not with us, therefore shall none of the prey that we have recovered be given unto them, save to every man his wife and his children: which let them carry away and be walking."
23 Then said David, "Ye shall not do so, my brethren, with that the LORD hath given us, and hath preserved us, and delivered the company that came against us, into our hands.
