Numbers 13:28-31

28But the people who live there are powerful, and the cities are fortified and very large. We even saw descendants of Anak there.

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

30Then Caleb silenced the people before Moses and said, “We should go up and take possession of the land, for we can certainly do it.”

31But the men who had gone up with him said, “We can’t attack those people; they are stronger than we are.”
