Deuteronomy 7:17-19

You’re going to think to yourselves, “Oh! We’re outnumbered ten to one by these nations! We’ll never even make a dent in them!” But I’m telling you, Don’t be afraid. Remember, yes, remember in detail what GOD, your God, did to Pharaoh and all Egypt. Remember the great contests to which you were eyewitnesses: the miracle-signs, the wonders, GOD’s mighty hand as he stretched out his arm and took you out of there. GOD, your God, is going to do the same thing to these people you’re now so afraid of.
