1 Samuel 8:10-12

10Then Samuel told the people who had asked him for a king everything the Lord had said.

11Samuel said, “These are the rights of a king: He will draft your sons, make them serve on his chariots and horses, and make them run ahead of his chariots.

12He will appoint them to be his officers over 1,000 or over 50 soldiers, to plow his ground and harvest his crops, and to make weapons and equipment for his chariots.
