Deuteronomy 4:34-35

Or has any [man-made] god ever tried to go and take for himself a nation from within another nation by trials, by signs and wonders and by war and by a mighty hand and by an outstretched arm and by great terrors, as the LORD your God did for you in Egypt before your [very] eyes? It was shown to you so that you might have [personal] knowledge and comprehend that the LORD is God; there is no other besides Him.
