1 Samuel 10:12

And one of the same place answered and said, But who is their father? Was it necessary for a person to have a special kind of father, in order to be accepted into the ranks of the prophets; what reason could be offered for excluding Saul from their company? Therefore it became a proverb, Is Saul also among the prophets? This proverb received further confirmation by an event in the later life of Saul, 1 Samuel 19:24.
