While the people continued to stand afar off Afraid of God's wrath, Moses drew near unto the thick darkness He was made to draw near; so the word is: Of himself he durst not have ventured into the thick darkness: if God had not called him, and encouraged him. And being gone into the thick darkness where God was, God there spoke, in his hearing only, all that follows from hence to the end of chapter 23., which is mostly an exposition of the ten commandments; and he was to transmit it to the people. The laws in these verses relate to God's worship. Ye have seen that I have talked with you from heaven Such was his wonderful condescension; ye shall not make gods of silver This repetition of the second commandment comes in here, because they were more addicted to idolatry than to any other sin.
