They did not see what he did to the Egyptian army, its horses and chariots, when he drowned them in the Red Sea as they were chasing you. The Lord ruined them forever.
No other god has ever taken for himself one nation out of another. But the Lord your God did this for you in Egypt, right before your own eyes. He did it with tests, signs, miracles, war, and great sights, by his great power and strength.
You saw for yourselves the troubles, signs, and miracles he did, how the Lord’s great power and strength brought you out of Egypt. The Lord your God will do the same thing to all the nations you now fear.
