1 Samuel 30:21-25

30:21 Then David approached the two hundred men who had been too exhausted to go with him, those whom they had left at the Wadi Besor. They went out to meet David and the people who were with him. When David approached the people, he asked how they were doing. 30:22 But all the evil and worthless men among those who had gone with David said, “Since they didn’t go with us, we won’t give them any of the loot we retrieved! They may take only their wives and children. Let them lead them away and be gone!”

30:23 But David said, “No! You shouldn’t do this, my brothers. Look at what the Lord has given us! He has protected us and has delivered into our hands the raiding party that came against us. 30:24 Who will listen to you in this matter? The portion of the one who went down into the battle will be the same as the portion of the one who remained with the equipment! Let their portions be the same!”

30:25 From that time onward it was a binding ordinance for Israel, right up to the present time.
