Numbers 13:31-33

31But the men who had gone up with him responded, “We can’t attack the people because they are stronger than we are!”

32So they gave a negative report to the Israelites about the land they had scouted: “The land we passed through to explore is one that devours its inhabitants, and all the people we saw in it are men of great size.

33We even saw the Nephilim there — the descendants of Anak come from the Nephilim! To ourselves we seemed like grasshoppers, and we must have seemed the same to them.”
