But one of the neighbors responded, "It doesn't matter who his father is; anyone can become a prophet." So that is the origin of the saying "Is Saul a prophet?"
References for 1 Samuel 10:12
When Saul had finished prophesying, he climbed the hill to the altar.
"Where in the world have you been?" Saul's uncle asked him."We went to look for the donkeys," Saul replied, "but we couldn't find them. So we went to the prophet Samuel to ask him where they were."
"Oh? And what did he say?" his uncle asked.
"He said the donkeys had been found," Saul replied. But Saul didn't tell his uncle that Samuel had anointed him to be king.
Later Samuel called all the people of Israel to meet before the LORD at Mizpah.
And he gave them this message from the LORD, the God of Israel: "I brought you from Egypt and rescued you from the Egyptians and from all of the nations that were oppressing you.
But though I have done so much for you, you have rejected me and said, 'We want a king instead!' Now, therefore, present yourselves before the LORD by tribes and clans."
So Samuel called the tribal leaders together before the LORD, and the tribe of Benjamin was chosen.
References for 1 Samuel 10:20
Then he brought each family of the tribe of Benjamin before the LORD, and the family of the Matrites was chosen. And finally Saul son of Kish was chosen from among them. But when they looked for him, he had disappeared!
So they asked the LORD, "Where is he?"And the LORD replied, "He is hiding among the baggage."
