Deuteronomy 4:35-36

King James Version

³⁵ Unto thee it was shewed, that thou mightest know that the Lord he is God; there is none else beside him.

³⁶ 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.
