So when he had turned his back to go from Samuel, God gave unto him another heart, and all these things came to pass that day.

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,

And it came about, that when he went away from Samuel, God gave him a changed heart: and all those signs took place that day.

And so, when he had turned his shoulder, so that he might go away from Samuel, God changed him to another heart. And all these signs occurred on that day.

And it was [so], that when he had turned his back to go from Samuel, God gave him another (d) heart: and all those signs came to pass that day.
(d) He gave him such virtues as were fitting for a king.

And it was so, that when he had turned his back to go from Samuel,.... When he had taken his leave of him, and set forward on his journey:
God gave him another heart; not in a moral or spiritual sense, not a new heart, and a new spirit, as in conversion, but in a civil sense, a right heart, a heart fit for government; filled with wisdom and prudence to rule a people; with courage and magnanimity to protect and defend them against their enemies, and fight for them; a heart not taken up with the affairs of husbandry, with care for his father's asses, and looking after his herds, but filled with concern for the civil welfare of Israel, and with schemes and contrivances for their good, and with warm resolutions to deliver them out of the hands of their enemies:
and all these signs came to pass that day; the two first, which are not particularly mentioned as fulfilled, being more private, as finding two men at Rachel's sepulchre, and meeting with three others going to Bethel, which came to pass just as they were described; and the third, which was more public, and gave Saul more reverence and respect among the people, is next particularly observed.

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.

when he had turned his back to go from Samuel, God gave him another heart--Influenced by the words of Samuel, as well as by the accomplishment of these signs, Saul's reluctance to undertake the onerous office was overcome. The fulfilment of the two first signs [1-Samuel 10:7-8] is passed over, but the third is specially described. The spectacle of a man, though more fit to look after his father's cattle than to take part in the sacred exercises of the young prophets--a man without any previous instruction, or any known taste, entering with ardor into the spirit, and skilfully accompanying the melodies of the sacred band, was so extraordinary a phenomenon, that it gave rise to the proverb, "Is Saul also among the prophets?" (see 1-Samuel 19:24). The prophetic spirit had come upon him; and to Saul it was as personal and experimental an evidence of the truth of God's word that had been spoken to him, as converts to Christianity have in themselves from the sanctifying power of the Gospel.

When Saul went away from Samuel, to return to Gibeah, "God changed to him another heart," - a pregnant expression for "God changed him, and gave him another heart" (see at 1-Samuel 10:6); and all these signs (the signs mentioned by Samuel) happened on that very day. As he left Samuel early in the morning, Saul could easily reach Gibeah in one day, even if the town where he had met with Samuel was situated to the south-west of Rachel's tomb, as the distance from that tomb to Gibeah was not more than three and a half or four hours.
