Numbers 13:31-33

31But the men who had gone into Canaan with him said, ‘These people are stronger than we are. So we cannot go and fight against them.’

32Those men gave to the Israelites a bad report about the land that they had explored. They said, ‘We went through that whole land and we explored it. The land seems to eat the people who live there! All the people that we saw there were very big and strong.

33We also saw descendants of the Nephilites there. And we felt like very small insects when we looked at them. And we seemed like very small insects to them too.’ (The descendants of Anak are also descendants of the Nephilites.)
