5 “After that you shall come to the hill of God, where is the garrison of the Philistines: and it shall happen, when you have come there to the city, that you shall meet a band of prophets coming down from the high place with a psaltery, and a tambourine, and a pipe, and a harp, before them; and they will be prophesying: 6 and the Spirit of Yahweh will come mightily on you, and you shall prophesy with them, and shall be turned into another man. 7 Let it be, when these signs have come to you, that you do as occasion shall serve you; for God is with you. 8 “You shall go down before me to Gilgal; and behold, I will come down to you, to offer burnt offerings, and to sacrifice sacrifices of peace offerings: you shall wait seven days, until I come to you, and show you what you shall do.”
9 It was so, that when he had turned his back to go from Samuel, God gave him another heart: and all those signs happened that day. 10 When they came there to the hill, behold, a band of prophets met him; and the Spirit of God came mightily on him, and he prophesied among them. 11 It happened, when all who knew him before saw that, behold, he prophesied with the prophets, then the people said one to another, “What is this that is come to the son of Kish? Is Saul also among the prophets?” 12 One of the same place answered, “Who is their father?” Therefore it became a proverb, “Is Saul also among the prophets?” 13 When he had made an end of prophesying, he came to the high place.

Commentary on 1 Samuel 10:1-8
(Read 1 Samuel 10:1-8)
The sacred anointing, then used, pointed at the great Messiah, or Anointed One, the King of the church, and High Priest of our profession, who was anointed with the oil of the Spirit, not by measure, but without measure, and above all the priests and princes of the Jewish church. For Saul's further satisfaction, Samuel gives him some signs which should come to pass the same day. The first place he directs him to, was the sepulchre of one of his ancestors; there he must be reminded of his own mortality, and now that he had a crown before him, must think of his grave, in which all his honour would be laid in the dust. From the time of Samuel there appears to have been schools, or places where pious young men were brought up in the knowledge of Divine things. Saul should find himself strongly moved to join with them, and should be turned into another man from what he had been. The Spirit of God changes men, wonderfully transforms them. Saul, by praising God in the communion of saints, became another man, but it may be questioned if he became a new man.
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.
