As Saul turned and started to leave, God gave him a new heart, and all Samuel’s signs were fulfilled that day.
When Saul and his servant arrived at Gibeah, they saw a group of prophets coming toward them. Then the Spirit of God came powerfully upon Saul, and he, too, began to prophesy.
When those who knew Saul heard about it, they exclaimed, “What? Is even Saul a prophet? How did the son of Kish become a prophet?”
And one of those standing there said, “Can anyone become a prophet, no matter who his father is?” So that is the origin of the saying “Is even Saul a prophet?”
