Exodus 20:21

¹⁹  And they said unto Moses, Speak thou with us, and we will hear: but let not God speak with us, lest we die.

²⁰  And Moses said unto the people, Fear not: for God is come to prove you, and that his fear may be before your faces, that ye sin not.

²¹  And the people stood afar off, and Moses drew near unto the thick darkness where God was.

²²  And the LORD said unto Moses, Thus thou shalt say unto the children of Israel, Ye have seen that I have talked with you from heaven.

²³  Ye shall not make with me gods of silver, neither shall ye make unto you gods of gold.
