1 Samuel 30:23-25

Young's Literal Translation

²³ And David saith, `Ye do not do so, my brethren, with that which Jehovah hath given to us, and He doth preserve us, and doth give the troop which cometh against us into our hand;

²⁴ and who doth hearken to you in this thing? for as the portion of him who was brought down into battle, so also [is] the portion of him who is abiding by the vessels -- alike they share.'

²⁵ And it cometh to pass from that day and forward, that he appointeth it for a statute and for an ordinance for Israel unto this day.
