Joshua 7:3-4

And they returned to Joshua, and said unto him, Let not all the people go up; but let about two or three thousand men go up and smite Ai; {and} make not all the people to labour thither; for they {are but} few. {about...: Heb. about two thousand men, or, about three thousand men} So there went up thither of the people about three thousand men: and they fled before the men of Ai.
