13:28 But the inhabitants are strong, and the cities are fortified and very large. Moreover we saw the descendants of Anak there. 13:29 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 banks of the Jordan.”

Numbers 13:32-33

13:32 Then they presented the Israelites with a discouraging report of the land they had investigated, saying, “The land that we passed through to investigate is a land that devours its inhabitants. All the people we saw there are of great stature. 13:33 We even saw the Nephilim there (the descendants of Anak came from the Nephilim), and we seemed liked grasshoppers both to ourselves and to them.”
