Numbers 13:28-31

28But the inhabitants are strong, and the cities are fortified and very large. Moreover we saw the descendants of Anak there.

29The Amalekites live in the land of the Negev; the Hittites, Jebusites, and Amorites live in the hill country; and the Canaanites live by the sea and along the banks of the Jordan.”

30Then Caleb silenced the people before Moses, saying, “Let us go up and occupy it, for we are well able to conquer it.”

31But the men who had gone up with him said, “We are not able to go up against these people, because they are stronger than we are!”
