Deuteronomy 7:17-21 ESV
“If you say in your heart, ‘These nations are greater than I. How can I dispossess them?’ you shall not be afraid of them but you shall remember what the LORD your God did to Pharaoh and to all Egypt, the great trials that your eyes saw, the signs, the wonders, the mighty hand, and the outstretched arm, by which the LORD your God brought you out. So will the LORD your God do to all the peoples of whom you are afraid. Moreover, the LORD your God will send hornets among them, until those who are left and hide themselves from you are destroyed. You shall not be in dread of them, for the LORD your God is in your midst, a great and awesome God.
