Deuteronomy 4:34-36

Amplified Bible

³⁴ 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? ³⁵ 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. ³⁶ Out of the heavens He let you hear His voice to discipline and admonish you; and on earth He let you see His great fire, and you heard His words from the midst of the fire.
