1st Samuel 10:12

9 And it came about, that when he went away from Samuel, God gave him a changed heart: and all those signs took place that day.

10 And when they came to Gibeah, a band of prophets came face to face with him; and the spirit of God came on him with power and he took his place among them as a prophet.

11 Now when Saul's old friends saw him among the band of prophets, the people said to one another, What has come to Saul, the son of Kish? Is even Saul among the prophets?

12 And one of the people of that place said in answer, And who is their father? So it became a common saying, Is even Saul among the prophets?

13 Then going away from the prophets, he came to the house.

14 And Saul's father's brother said to him and his servant, Where have you been? And he said, Searching for the asses: and when we saw no sign of them, we came to Samuel.

15 Then he said, And what did Samuel say to you?
