101 Then Samuel took a flask of oil, poured it on Saul's head, and kissed him. He said, "Do you see what this means? God has anointed you prince over his people. 2 After you leave me today, as you get closer to your home country of Benjamin, you'll meet two men near Rachel's Tomb. They'll say, 'The donkeys you went to look for are found. Your father has forgotten about the donkeys and is worried about you, wringing his hands - quite beside himself!' 3 "Leaving there, you'll arrive at the Oak of Tabor. There you'll meet three men going up to worship God at Bethel. One will be carrying three young goats, another carrying three sacks of bread, and the third a jug of wine.
Matthew Henry's Commentary on 1 Samuel 10:1-3
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.
