1 Samuel 13:5-9

Now the Philistines assembled to fight with Israel, thirty thousand chariots and six thousand horsemen, and people like the sand which is on the seashore in abundance; and they came up and camped in Michmash, east of Beth-aven.

When the men of Israel saw that they were in trouble (for the people were hard-pressed), then the people kept themselves hidden in caves, in crevices, in cliffs, in crypts, and in pits.

And some of the Hebrews crossed the Jordan into the land of Gad and Gilead. But as for Saul, he was still in Gilgal, and all the people followed him, trembling.

Now he waited for seven days, until the appointed time that Samuel had set, but Samuel did not come to Gilgal; and the people were scattering from him.

So Saul said, “Bring me the burnt offering and the peace offerings.” And he offered the burnt offering.
