1 Samuel 30:21-25

21Then David returned to the brook Besor and met up with the 200 men who had been left behind because they were too exhausted to go with him. They went out to meet David and his men, and David greeted them joyfully.

22But some evil troublemakers among David’s men said, “They didn’t go with us, so they can’t have any of the plunder we recovered. Give them their wives and children, and tell them to be gone.”

23But David said, “No, my brothers! Don’t be selfish with what the Lord has given us. He has kept us safe and helped us defeat the band of raiders that attacked us.

24Who will listen when you talk like this? We share and share alike—those who go to battle and those who guard the equipment.”

25From then on David made this a decree and regulation for Israel, and it is still followed today.
