Ye shall observe to do - He who marks not the word of God is never likely to fulfill the will of God.
Ye shall not turn aside to the right hand or to the left - The way of truth and righteousness is a right line; a man must walk straight forward who wishes to go to glory; no crooked or devious path ever led to God or happiness.
These verses contain a much fuller narrative of the events briefly described in Exodus 20:18-21. Here it is important to call attention to the fact that it was on the entreaties of the people that Moses had taken on him to be the channel of communication between God and them. God approved Deuteronomy 5:28 the request of the people, because it showed a feeling of their own unworthiness to enter into direct communion with God. The terrors of Sinai had done their work; they had awakened the consciousness of sin.
