Ye shall walk in all the ways, etc. - God never gave a commandment to man which he did not design that he should obey. He who selects from the Divine testimonies such precepts as he feels but little inclination to transgress, and lives in the breach of others, sins against the grand legislative authority of God, and shall be treated as a rebel.
That ye may live - תחיון ticheyun, that ye may enjoy life, (for the paragogic nun, at the end of the word, deepens the sense), that it may be well with you לכם ותוב vetob lachem, and good shall be to you - God will prosper you in all things essential to the welfare of your bodies, and the salvation of your souls.
That ye may prolong your days in the land - That ye may arrive at a good old age, and grow more and more meet for the inheritance among the saints in light.
On this very important verse we may remark, a long life is a great blessing, if a man live to God, because it is in life, and in life alone, that a preparation for eternal glory may be acquired. Those who wish to die soon, have never yet learned to live, and know not the value of life or time. Many have a vain hope that they shall get either in death, or in the other world, a preparation for glory. This is a fatal error. Here, alone, we may acquaint ourselves with God, and receive that holiness without which none can see him. Reader, be thankful to him that thou art still in a state of probation; and pray that thou mayest live for eternity.
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.
