Numbers 13:31

27 And they gave this account to Moses: “We went into the land to which you sent us, and indeed, it is flowing with milk and honey. Here is some of its fruit!

28 Nevertheless, the people living in the land are strong, and the cities are large and fortified. We even saw the descendants of Anak there.

29 The Amalekites live in the land of the Negev; the Hittites, Jebusites, and Amorites live in the hill country; and the Canaanites live by the sea and along the Jordan.”

30 Then Caleb quieted the people before Moses and said, “We must go up and take possession of the land, for we can certainly conquer it!”

31 But the men who had gone up with him replied, “We cannot go up against the people, for they are stronger than we are!”

32 So they gave the Israelites a bad report about the land that they had spied out: “The land we explored devours its inhabitants, and all the people we saw there are great in stature.

33 We even saw the Nephilim there—the descendants of Anak that come from the Nephilim! We seemed like grasshoppers in our own sight, and we must have seemed the same to them!”
