1 Samuel 8:10-12

10Samuel spoke to the people who had asked him to give them a king. He told them everything that the Lord had said to him.

11Samuel said to them, ‘This is how the king will rule over you: He will take your sons to be his soldiers. They will ride his horses and they will drive his chariots. They will have to run in front of his own chariot.

12The king will choose some of your sons to be officers in his army. Some will be leaders of 1,000 soldiers. Others will be leaders of 50 soldiers. Some of your sons will have to plough the king's fields. They will have to cut his crops at harvest time. They will have to make weapons for the king to fight wars. They will have to fix his chariots.
