1 Samuel 10:7-17 NLT

7 After these signs take place, do whatever you think is best, for God will be with you.
8 Then go down to Gilgal ahead of me and wait for me there seven days. I will join you there to sacrifice burnt offerings and peace offerings. When I arrive, I will give you further instructions."
9 As Saul turned and started to leave, God changed his heart, and all Samuel's signs were fulfilled that day.
10 When Saul and his servant arrived at Gibeah, they saw the prophets coming toward them. Then the Spirit of God came upon Saul, and he, too, began to prophesy.
11 When his friends heard about it, they exclaimed, "What? Is Saul a prophet? How did the son of Kish become a prophet?"
12 But one of the neighbors responded, "It doesn't matter who his father is; anyone can become a prophet." a So that is the origin of the saying "Is Saul a prophet?"
