Joshua 7:2-5

Now Joshua sent men from Jericho to Ai, which is near Beth-aven, east of Bethel, and said to them, “Go up and spy out the land.” So the men went up and spied out Ai. Then they returned to Joshua and said to him, “Do not make all the people go up [to fight]; have only about two thousand or three thousand men go up and attack Ai; do not make the entire army go up there, for they [of Ai] are few.” So about three thousand men from the sons of Israel went up there, but they fled [in retreat] from the men of Ai. The men of Ai killed about thirty-six of Israel’s men, and chased them from the gate as far as [the bluffs of] Shebarim and struck them down as they descended [the steep pass], so the hearts of the people melted [in despair and began to doubt God’s promise] and became like water (disheartened).
