1 Samuel 10:23-26

(23) And they ran and fetched him thence: and when he stood among the people, he was higher than any of the people from his shoulders and upward. (24) And Samuel said to all the people, See ye him whom the LORD hath chosen, that there is none like him among all the people? And all the people shouted, and said, God save the king. (25) Then Samuel told the people the manner of the kingdom, and wrote it in a book, and laid it up before the LORD. And Samuel sent all the people away, every man to his house. (26) And Saul also went home to Gibeah; and there went with him a band of men, whose hearts God had touched.

The people seem to have been struck with his majectic appearance, and therefore hailed him as king. And some so much regarded him as to attend his person home. By God touching their hearts, I apprehend is meant as God touched his, that is, inclined them to respect him. No saving change of grace is meant. Not the regeneration of the heart by grace. The subject refers only to things of a temporal nature.
