1 Samuel 13:7,8

Some of the Hebrews went over Jordan They fled as far as they could from the present danger, even into the country of the two tribes and a half. All the people followed him trembling That is, all that were left, who, it appears, were not many. He tarried seven days Not seven complete days, for the last day was not finished. According to the set time that Samuel had appointed This seems to refer to the command given two years before, and recorded 1 Samuel 10:8: see the note on that verse. But Samuel came not to Gilgal So soon as Saul expected him.
