1 Samuel 30:22-25

But the evil men and troublemakers among those who followed David said, “Since these two hundred men didn’t go with us, we shouldn’t give them any of the things we recovered. Just let each man take his wife and children and go.” David answered, “No, my brothers. Don’t do that after what the LORD has given us. He has protected us and given us the enemy who attacked us. Who will listen to what you say? The share will be the same for the one who stayed with the supplies as for the one who went into battle. All will share alike.” David made this an order and rule for Israel, which continues even today.
