9 And it hath been, at his turning his shoulder to go from Samuel, that God turneth to him another heart, and all these signs come on that day, 10 and they come in thither to the height, and lo, a band of prophets—to meet him, and prosper over him doth the Spirit of God, and he prophesieth in their midst.
Matthew Henry's Commentary on 1 Samuel 10:9-10
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.
