Deuteronomy 7:17-19

You may say to yourselves, “These nations are stronger than we are. How can we drive them out?” But do not be afraid of them; remember well what the LORD your God did to Pharaoh and to all Egypt. You saw with your own eyes the great trials, the signs and wonders, the mighty hand and outstretched arm, with which the LORD your God brought you out. The LORD your God will do the same to all the peoples you now fear.
