The "Sabbath" was a recognized institution long before the days of Moses. Traces of its strict and sacred observance in the ancestral home of Abraham are disclosed in the Assyrian records unearthed in these later days. And now that the Lord, at Sinai, is drawing away his covenant people from the sins and errors of their fathers and neighbors, he reminds them that there is good in some of the observances of the past, which they are not to forsake or forget. "Remember," therefore he says, "the sabbath day to keep it holy"--as your fathers in all their polytheism had a care to observe it of old. Bear _that_ institution in mind, as worth your remembering. And here again there is affirmed a principle which is for all time and for all people. Although the reason for setting apart one day above another for rest and worship is not on the surface of things, the experiences of mankind, as well as the teachings of God's Word, go to show that there is such a reason below the surface. In the long run, man can do more work, and do it better, in six days of a week, than he can in seven; and unless a man worships God at stated times, he is not likely to worship him at all. So it is that God makes it a part of his loving covenant between himself and his people, that ever and always they shall worship him statedly, as well as worship him sincerely, spiritually, and solely; because without this stated recognition of the covenant, the covenant itself would be forgotten. And now we come to the fifth of the ten covenant requirements: "Honor thy father and thy mother." This also is in the affirmative form, and for a very good reason. God is here declaring, as it were, that those who are in legitimate authority are so far his representatives. He wants it understood that while no other gods are in existence, even in a subordinate place in the universe, he has his representatives in various spheres of human government and rule, and they are to be honored accordingly by his covenant people. We are accustomed to speak of the division of the Ten Commandments into two tables, the first comprising four requirements, and the second six; but it will be seen that this fifth requirement belongs with the preceding four in the group of those which look God-ward. It is as though the one table pointed upward from ourselves, while the other pointed outward. We are to honor those who are over us in the Lord, not as our fellows, but as our superiors; not because of what they are as men, but because they are, within the scope of their rule, the representatives of our God.
