And the LORD said unto Joshua, Fear not, neither be dismayed: take all the people of war with you, and arise, go up to Ai: see, I have given into your hand the king of Ai, and his people, and his city, and his land:
And he shall be as a sanctuary; but a stone of stumbling and a rock of offense to both the houses of Israel, for a trap and for a snare to the inhabitants of Jerusalem.
And the men of Gibeon sent unto Joshua to the camp to Gilgal, saying, Abandon not your hand from your servants; come up to us quickly, and save us, and help us: for all the kings of the Amorites that dwell in the mountains are gathered together against us.
So Joshua arose, and all the people of war, to go up against Ai: and Joshua chose out thirty thousand mighty men of valor, and sent them away by night.
