19 and said to Moses, "You speak to us, and we will listen; but do not let God speak to us, lest we die." 20 Moses said to the people, "Do not fear, for God has come to test you, that the fear of him may be before you, that you may not sin." 21 The people stood far off, while Moses drew near to the thick darkness where God was.

22 And the Lord said to Moses, "Thus you shall say to the people of Israel: 'You have seen for yourselves that I have talked with you from heaven. 23 You shall not make gods of silver to be with me, nor shall you make for yourselves gods of gold.

Commentary on Exodus 20:18-21

(Read Exodus 20:18-21)

This law, which is so extensive that we cannot measure it, so spiritual that we cannot evade it, and so reasonable that we cannot find fault with it, will be the rule of the future judgment of God, as it is for the present conduct of man. If tried by this rule, we shall find our lives have been passed in transgressions. And with this holy law and an awful judgment before us, who can despise the gospel of Christ? And the knowledge of the law shows our need of repentance. In every believer's heart sin is dethroned and crucified, the law of God is written, and the image of God renewed. The Holy Spirit enables him to hate sin and flee from it, to love and keep this law in sincerity and truth; nor will he cease to repent.

Commentary on Exodus 20:22-26

(Read Exodus 20:22-26)

Moses having entered into the thick darkness, God there spake in his hearing all that follows from hence to the end of chap. 23, which is mostly an exposition of the ten commandments. The laws in these verses relate to God's worship. The Israelites are assured of God's gracious acceptance of their devotions. Under the gospel, men are encouraged to pray every where, and wherever God's people meet in his name to worship him, he will be in the midst of them; there he will come unto them, and will bless them.
