Deuteronomy 4:33-36

Thomson(i) 33 Hath any nation heard the voice of the living God, speaking out of the midst of the fire, as thou hast heard, and are still alive? 34 Or hath God come, and made trial to take for himself a nation out of the midst of a nation, by trials, and by signs, and by wonders, and by war, and with a strong hand, and an outstretched arm, and with great visions, according to all that the Lord our God hath done in Egypt, before thine eyes? 35 So that thou must needs know that the Lord thy God is very God, and that there is none else besides him. 36 From heaven he caused his voice to be heard to instruct thee; and on earth he shewed thee his great fire. And thou hast heard his words out of the midst of the fire.
