1 Samuel 13:5-6

LEB(i) 5 And the Philistines assembled to fight with Israel, thirty thousand chariots and six thousand horsemen and an army as numerous as sand which is on the seashore. And they came up and encamped at Micmash, east of Beth Aven. 6 When the men of Israel saw that it was too difficult* for them, because the army was hard pressed, the people hid themselves in the caves, in the thorn bushes, in the cliffs, in the vaults* and in the wells.
