9 When he turned his back to leave Samuel, God gave him another heart. And all these signs came to pass that day. 10 When they came to Gibeah,[1] behold, a group of prophets met him, and the Spirit of God rushed upon him, and he prophesied among them. 11 And when all who knew him previously saw how he prophesied with the prophets, the people said to one another, "What has come over the son of Kish? Is Saul also among the prophets?" 12 And a man of the place answered, "And who is their father?" Therefore it became a proverb, "Is Saul also among the prophets?" 13 When he had finished prophesying, he came to the high place. 14 Saul's uncle said to him and to his servant, "Where did you go?" And he said, "To seek the donkeys. And when we saw they were not to be found, we went to Samuel." 15 And Saul's uncle said, "Please tell me what Samuel said to you." 16 And Saul said to his uncle, "He told us plainly that the donkeys had been found." But about the matter of the kingdom, of which Samuel had spoken, he did not tell him anything.

Commentary on 1 Samuel 10:9-16

(Read 1 Samuel 10:9-16)

The signs Samuel had given Saul, came to pass punctually; he found that God had given him another heart, another disposition of mind. Yet let not an outward show of devotion, and a sudden change for the present, be too much relied on; Saul among the prophets was Saul still. His being anointed was kept private. He leaves it to God to carry on his own work by Samuel, and sits still, to see how the matter will fall.
