Deuteronomy 7:1, 19

“When the LORD your God brings you into the land you are about to enter and occupy, he will clear away many nations ahead of you: the Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites. These seven nations are greater and more numerous than you.

Remember the great terrors the LORD your God sent against them. You saw it all with your own eyes! And remember the miraculous signs and wonders, and the strong hand and powerful arm with which he brought you out of Egypt. The LORD your God will use this same power against all the people you fear.
