1 Samuel 30:18-30

So David recovered all that the Amalekites had taken, and rescued his two wives. Nothing of theirs was missing whether small or great, sons or daughters, spoil or anything that had been taken; David recovered it all. So David captured all the flocks and herds [which the enemy had], and [the people] drove those animals before him and said, “This is David’s spoil.” David came to the two hundred men who were so exhausted that they could not follow him and had been left at the brook Besor [with the provisions]. They went out to meet David and the people with him, and when he approached the people, he greeted them. Then all the wicked and worthless men among those who went with David said, “Because they did not go with us, we will give them none of the spoil that we have recovered, except that each man may take his wife and children away and leave.” David said, “You must not do so, my brothers, with what the LORD has given us. He has kept us safe and has handed over to us the band [of Amalekites] that came against us. And who will listen to you in regard to this matter? For as is the share of him who goes down into the battle, so shall his share be who stays by the provisions and supplies; they shall share alike.” So from that day forward he made it a statute and an ordinance for Israel to this day. When David came to Ziklag, he sent part of the spoil to the elders of Judah, his friends, saying, “Here is a blessing (gift) for you from the spoil of the enemies of the LORD: For those in Bethel, Ramoth of the Negev, Jattir, Aroer, Siphmoth, Eshtemoa, Racal, the cities of the Jerahmeelites, the cities of the Kenites, Hormah, Bor-ashan, Athach
