And the LORD said to Joshua, Fear not, neither be you 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 for a sanctuary; but for a stone of stumbling and for a rock of offense to both the houses of Israel, for a gin and for a snare to the inhabitants of Jerusalem.
And the men of Gibeon sent to Joshua to the camp to Gilgal, saying, Slack 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.
