And the LORD said unto Moses, Speak unto Aaron your brother, that he come not at all times into the holy place within the veil before the mercy seat, which is upon the ark; that he die not: for I will appear in the cloud upon the mercy seat.
And you came near and stood at the foot of the mountain; and the mountain burned with fire unto the midst of heaven, with darkness, clouds, and thick darkness.
These words the LORD spoke unto all your assembly in the mount out of the midst of the fire, of the cloud, and of the thick darkness, with a great voice: and he added no more. And he wrote them in two tables of stone, and delivered them unto me.
