He came to the high place - I suppose this to mean the place where Saul's father lived; as it is evident the next verse shows him to be at home.

And when he had made an end of prophesying,.... For, as Procopius Gazaeus observes, he had not the gift of prophecy always; it did not continue with him, but, like that of the seventy elders in the times of Moses, it was designed to make him respectable among the people, and to be taken notice of as a person that God had honoured with a peculiar gift, that so, when he should be chosen king, they would the more readily receive him:
he came to the high place; to return thanks to God for the gift bestowed on him, and for that high honour and dignity he was raised unto, of which he had private knowledge; and to pray God to fit him more and more for government, and to, assist him in it, and help him to discharge his office in a wise and faithful manner.

High place - Returning thither with the prophets, to praise God for these wonderful favours, and to beg counsel and help from God in this high business.
