Deuteronomy 4:35-37

The Voice

³⁵ You saw all this so you would know the Eternal is the only God who truly exists. There is no other. ³⁶ You heard His voice from heaven as He admonished you; He showed you His blazing fire on the earth, and you heard His words from inside that fire—all at His will. ³⁷ Because He loved your ancestors, He’s also committed to their descendants who came after them, and that’s why He personally brought you out of Egypt by His own great power.
