1 Samuel 8:1-6

And it came about when Samuel was old that he appointed his sons as judges over Israel. Now the name of his firstborn was Joel, and the name of his second, Abijah; they were judging in Beersheba. His sons, however, did not walk in his ways, but turned aside after dishonest gain, took bribes, and perverted justice. Then all the elders of Israel gathered together and came to Samuel at Ramah and said to him, “Look, you have grown old, and your sons do not walk in your ways. Now appoint us a king to judge us [and rule over us] like all the other nations.” But their demand displeased Samuel when they said, “Give us a king to judge and rule over us.” So Samuel prayed to the LORD.
