Deuteronomy 7:17-21

17“If you say to yourself, ‘These nations are greater than I; how can I drive them out?’

18do not be afraid of them. Be sure to remember what the Lord your God did to Pharaoh and all Egypt:

19the great trials that you saw, the signs and wonders, the strong hand and outstretched arm, by which the Lord your God brought you out. The Lord your God will do the same to all the peoples you fear.

20The Lord your God will also send hornets against them until all the survivors and those hiding from you perish.

21Don’t be terrified of them, for the Lord your God, a great and awesome God, is among you.
