Let us, for instance, compare the two scriptures in reference to the subject of the Sabbath. In Exodus xx, we read, "Remember the Sabbath day, to keep it holy. Six days shalt thou labor, and do all thy work; but the seventh day is the Sabbath of the Lord thy God; in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy man-servant, nor thy maid-servant, nor thy cattle, nor thy stranger that is within thy gates: _for in six days the Lord made heaven and earth, the sea, and all that in them is_, and rested the seventh day; wherefore the Lord blessed the Sabbath day, and hallowed it." In Deuteronomy v, we read, "Keep the Sabbath day to sanctify it, _as the Lord thy God hath commanded thee_. Six days thou shalt labor, and do all thy work; but the seventh day is the Sabbath of the Lord thy God; in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy man-servant, nor thy maid-servant, _nor thine ox, nor thine ass_, nor any of thy cattle, nor thy stranger that is within thy gates; that thy man-servant and thy maid-servant may rest as well as thou. _And remember that thou wast a servant in the land of Egypt, and that the Lord thy God brought thee out thence, through a mighty hand and by a stretched-out arm; therefore the Lord thy God commanded thee to keep the Sabbath day._" (Ver. 12-15.) Now, the reader can see at a glance the difference between the two passages. In Exodus xx, the command to keep the Sabbath is grounded on _creation_; in Deuteronomy v, it is grounded on _redemption_, without any allusion to creation at all. In short, the points of difference arise out of the distinct character of each book, and are perfectly plain to every spiritual mind. With regard to the institution of the Sabbath, we must remember that it rests wholly upon the direct authority of the word of God. Other commandments set forth plain moral duties. Every man knows it to be morally wrong to kill or steal; but as to the observance of the Sabbath, no one could possibly recognize it as a duty had it not been distinctly appointed by divine authority. Hence its immense importance and interest. Both in our chapter and in Exodus xx. it stands side by side with all those great moral duties which are universally recognized by the human conscience. And not only so, but we find, in various other scriptures, that the Sabbath is singled out and presented, with special prominence, as a precious link between Jehovah and Israel, a seal of His covenant with them, and a powerful test of their devotedness to Him. Every one could recognize the moral wrong of theft and murder; only those who loved Jehovah and His word would love and honor His Sabbath.
