Numbers 13:31-33

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!”

32Then they presented the Israelites with a discouraging report of the land they had investigated, saying, “The land that we passed through to investigate is a land that devours its inhabitants. All the people we saw there are of great stature.

33We even saw the Nephilim there (the descendants of Anak came from the Nephilim), and we seemed liked grasshoppers both to ourselves and to them.”
