Samuel had problems because of his undisciplined sons, a common trait in many families.

1 Samuel 8:1. And it was, when Samuel was old, that he made his sons judges over Israel. 2. Now the name of his firstborn was Joel, and the name of his second, Abijah. They were judges in Beer Sheba. 3. But his sons did not walk in his Ways, but turned aside after unjust gain and took bribes and perverted justice. 4. Then all the elders of Israel gathered themselves together and came to Samuel at Ramah 5. and said to him, Behold, you are old and your sons are not walking in your ways. Now set a king for us to judge us like all the nations. 6. But the thing displeased Samuel when they said, Give us a king to judge us. And Samuel prayed to the LORD*. 7. And the LORD* said to Samuel, listen to the voice of the people in all that they say to you, for they have not rejected you, but they have rejected Me, that I should not reign over them.
