Then Samuel told the people the manner of the kingdom, and wrote it in a book, and laid it up before Yahweh. Samuel sent all the people away, every man to his house.
The lot (1 Samuel 10:20) showed all Israel that Saul was God’s choice, not Samuel’s (cf. Joshua 7:14-18). That is, he was the king God permitted (Proverbs 16:33). Was Saul hiding because he was humble or because he was afraid to assume the mantel of leadership? My judgment is that he was humble since there are other indications of this quality in chapters 9 and 10 (cf. Proverbs 25:6-7).
