101 Samuel took a vial of oil and poured it on his head, and kissed him; he said, "The Lord has anointed you ruler over his people Israel. You shall reign over the people of the Lord and you will save them from the hand of their enemies all around. Now this shall be the sign to you that the Lord has anointed you ruler over his heritage:

Matthew Henry's Commentary on 1 Samuel 10:1

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.
