Numbers 13:31-33

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

32And they spread among the Israelites a bad report about the land they had explored. They said, “The land we explored devours those living in it. All the people we saw there are of great size.

33We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them.”
