1 Samuel 10:12

One of the same place, Heb. one from thence, i.e. one of the company there present, or one of the prophets there prophesying. Who is their father? who is the father of all these prophets of whom you speak, and among whom Saul now is one? who is it that instructs and inspires them with this holy art, but God? They have it not from their natural parents, nor from their civil education, but by inspiration from God, who, when he pleaseth, can inspire Saul, or any other man, with the same skill. And therefore wonder not at this matter, but give God the glory of it. Father is here put for teacher, or instructer, as it is used; as Genesis 4:20,21 Mt 23:9 1 Corinthians 4:15. And hence the scholars are called sons of the prophets. It became a proverb, used when any strange, unlikely, or unexpected thing happened.
