Deuteronomy 4:34-35

34Has any god ever tried to take for himself one nation out of another nation, by testings, by signs and wonders, by war, by a mighty hand and an outstretched arm, or by great and awesome deeds, like all the things the LORD your God did for you in Egypt before your very eyes? 35You were shown these things so that you might know that the LORD is God; besides him there is no other.
