1 Samuel 13:6-8

6And the men of Israel saw that they were in a strait (for the people were distressed); and the people hid themselves in caves, and in thickets, and in cliffs, and in strongholds, and in pits.

7And the Hebrews went over the Jordan into the land of Gad and Gilead. And Saul was yet in Gilgal, and all the people followed him trembling.

8And he waited seven days, according to the set time that Samuel [had appointed]; but Samuel did not come to Gilgal; and the people were scattered from him.
