Deuteronomy 9:1-2
Theological Justification of the Conquest
9:1 Listen, Israel: Today you are about to cross the Jordan so you can dispossess the nations there, people greater and stronger than you who live in large cities with extremely high fortifications.
9:2 They include the Anakites, a numerous and tall people whom you know about and of whom it is said, “Who is able to resist the Anakites?”
Numbers 13:28-33
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.”
13:30 Then Caleb silenced the people before Moses, saying, “Let us go up and occupy it, for we are well able to conquer it.”
13:31 But the men who had gone up with him said, “We are not able to go up against these people, because they are stronger than we are!”
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.”
