Deuteronomy 5:22-24

YLT(i) 22 `These words hath Jehovah spoken unto all your assembly, in the mount out of the midst of the fire, of the cloud, and of the thick darkness—a great voice; and He hath not added, and He writeth them on two tables of stone, and giveth them unto me.
23 `And it cometh to pass as ye hear the voice out of the midst of the darkness, and of the mountain burning with fire, that ye come near unto me, all the heads of your tribes, and your elders, 24 and say, Lo, Jehovah our God hath shewed us His honour, and His greatness; and His voice we have heard out of the midst of the fire; this day we have seen that God doth speak with man—and he hath lived.
