Deuteronomy 4:34 (KJV)

For ask now of the days that are past, which were before thee, since the day that God created man upon the earth, and ask from the one side of heaven unto the other, whether there hath been any such thing as this great thing is, or hath been heard like it?

Did ever people hear the voice of God speaking out of the midst of the fire, as thou hast heard, and live?

Or hath God assayed to go and take him a nation from the midst of another nation, by temptations, by signs, and by wonders, and by war, and by a mighty hand, and by a stretched out arm, and by great terrors, according to all that the Lord your God did for you in Egypt before your eyes?

Unto thee it was shewed, that thou mightest know that the Lord he is God; there is none else beside him.

Out of heaven he made thee to hear his voice, that he might instruct thee: and upon earth he shewed thee his great fire; and thou heardest his words out of the midst of the fire.
