1 Samuel 30:21-25

Then David came to the two hundred men who had been too exhausted to follow him and who were left behind at the Besor Valley. They came out to meet David and the men with him. As David and his men approached, he asked them how they were. But all the evil men and troublemakers among David’s followers said, “Because they did not go out with us, we will not share with them the plunder we recovered. However, each man may take his wife and children and go.” David replied, “No, my brothers, you must not do that with what the LORD has given us. He has protected us and delivered into our hands the raiding party that came against us. Who will listen to what you say? The share of the man who stayed with the supplies is to be the same as that of him who went down to the battle. All will share alike.” David made this a statute and ordinance for Israel from that day to this.
