5 After that thou shalt come to the hill of God, where are the outposts of the Philistines; and it shall come to pass, when thou comest thither, into the city, that thou shalt meet a company of prophets coming down from the high place with lute and tambour and pipe and harp before them; and they themselves prophesying. 6 And the Spirit of Jehovah will come upon thee, and thou shalt prophesy with them, and shalt be turned into another man. 7 And it shall be, when these signs shall come to thee, thou shalt do as thy hand shall find; for God is with thee. 8 And thou shalt go down before me to Gilgal; and behold, I will come down to thee, to offer up burnt-offerings, [and] to sacrifice sacrifices of peace-offerings: seven days shalt thou wait, until I come to thee and inform thee what thou shalt do.
9 And it was [so] that when he turned his back to go away from Samuel, God gave him another heart; and all those signs came to pass that day. 10 And when they came thither to the hill, behold, a company of prophets met him; and the Spirit of God came upon him, and he prophesied among them. 11 And it came to pass, when all that knew him before saw that, behold, he prophesied among the prophets, then the people said one to another, What is this that has happened to the son of Kish? Is Saul also among the prophets? 12 And a man of that place answered and said, But who is their father? Therefore it became a proverb, Is Saul also among the prophets? 13 And when he had ended 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.
