Numbers 13:28-31

28But the people who live in the land are strong, and the cities are fortified (walled) and very large; moreover, we saw there the descendants of Anak [people of great stature and courage].

29[The people descended from] Amalek live in the land of the Negev (South country); the Hittite, the Jebusite, and the Amorite live in the hill country; and the Canaanites live by the [Dead] Sea and along the side of the Jordan.”

30Then Caleb quieted the people before Moses, and said, “Let us go up at once and take possession of it; for we will certainly conquer it.”

31But the men who had gone up with him said, “We are not able to go up against the people [of Canaan], for they are too strong for us.”
