Exodus 20:22

And the Lord said unto Moses ,.... When Moses was come near the thick darkness where God was:

thus thou shalt say unto the children of Israel ; at his return unto them, and which he was to deliver in the name of God, and as his words:

ye have seen that I have talked with you from heaven ; descending from heaven on Mount Sinai in a cloud and fire, he talked with them out of the cloud and fire, and delivered to them with an audible voice the above ten commands; the cloud and fire they saw with their eyes, and the words expressed from thence they heard with their ears; or heaven may mean the air on the top of Sinai, from whence Jehovah spoke.
