I Samuel 13:5-10

Then the Philistines gathered together to fight with Israel, thirty thousand chariots and six thousand horsemen, and people as the sand which is on the seashore in multitude. And they came up and encamped in Michmash, to the east of Beth Aven. When the men of Israel saw that they were in danger (for the people were distressed), then the people hid in caves, in thickets, in rocks, in holes, and in pits. And some of the Hebrews crossed over the Jordan to the land of Gad and Gilead. As for Saul, he was still in Gilgal, and all the people followed him trembling. Then he waited seven days, according to the time set by Samuel. But Samuel did not come to Gilgal; and the people were scattered from him. So Saul said, “Bring a burnt offering and peace offerings here to me.” And he offered the burnt offering. Now it happened, as soon as he had finished presenting the burnt offering, that Samuel came; and Saul went out to meet him, that he might greet him.
