Numbers 13:32-33

32So they brought to the people of Israel a bad report of the land that they had spied out, saying, "The land, through which we have gone to spy it out, is a land that devours its inhabitants, and all the people that we saw in it are of great height.

33And there we saw the Nephilim (the sons of Anak, who come from the Nephilim), and we seemed to ourselves like grasshoppers, and so we seemed to them."
