1 Samuel 13:5-7

5Meanwhile the Philistines assembled themselves to fight with Israel: 30,000 chariots, 6,000 horsemen and troops as numerous as the sand on the seashore. They marched up and camped in Michmas, east of Beth-aven.

6When the men of Israel saw that they were in trouble, because the people were hard-pressed, they hid in caves, thickets, cliffs, crevices and pits.

7Some of the Hebrews even crossed over the Jordan to the land of Gad and Gilead. But as for Saul, he was still in Gilgal, but all the people following him were trembling.
