5:15 keep the sabbath day. The most significant difference between the parallel records of the ten commandments in Exodus and Deuteronomy is in the reason given for keeping the sabbath. In Exodus it was said to be in remembrance of the completed creation, honoring God as Creator of all things. Here in Deuteronomy, the reason was in remembrance of their miraculous deliverance from slavery in Egypt, honoring God as Redeemer and Savior. Thus, in our own day, it is appropriate that we also observe every seventh day as a day to honor God both as Creator and Savior, remembering both His finished creation (Genesis 2:1-3), and His completed redemption (John 19:30).
