1 Samuel 8:10-12

10So Samuel passed on the Lord’s warning to the people who were asking him for a king.

11“This is how a king will reign over you,” Samuel said. “The king will draft your sons and assign them to his chariots and his charioteers, making them run before his chariots.

12Some will be generals and captains in his army, some will be forced to plow in his fields and harvest his crops, and some will make his weapons and chariot equipment.
