Numbers 13:31-33

³¹But the men that went up with him said: 'We are not able to go up against the people; for they are stronger than we.'

³²And they spread an evil report of the land which they had spied out unto the children of Israel, saying: 'The land, through which we have passed to spy it out, is a land that eateth up the inhabitants thereof; and all the people that we saw in it are men of great stature.

³³And there we saw the Nephilim, the sons of Anak, who come of the Nephilim; and we were in our own sight as grasshoppers, and so we were in their sight.'
