1 Samuel 13:4-6

Amplified Bible

⁴ All Israel heard that Saul had defeated the Philistine garrison, and also that Israel had become despicable to the Philistines. And the people were summoned to join Saul at Gilgal.

⁵ Now the Philistines gathered to fight against Israel, 30,000 chariots and 6,000 horsemen, and troops in multitude, like sand on the seashore. They came up and camped at Michmash, east of Beth-aven. ⁶ When the men of Israel saw that they were in a tight situation (for their troops were hard-pressed), they hid in caves, in thickets, in cellars, and in [dry] cisterns (pits).
