Genesis summarizes, "Thus the heavens and the earth were completed, and all their hosts" (2:1). But is this just an Old Testament historical reference? Actually, "these things happened as examples for us" (1Co 10:6). Also, Jesus "explained to them the things concerning Himself in all the Scriptures" (Lk 24:27). Therefore, there is a continuity. These types in Genesis are built upon and apply today. "By the seventh day God completed His work which He had done" (Ge 2:2). "He ceased from labor" (Ex 31:17), which was effort applicable to "His works which God had created and made" (Ge 2:3). In it God was "refreshed" (Ex 31:17). It was separate and special because "God blessed the seventh day" (Ge 2:3). Furthermore, God "sanctified it, because in it He rested from all His works" (:3). It then became a "sabbath observance, a holy sabbath to the Lord" (Ex 16:23). But it was not just a one-way requirement of man's responsibility to worship God. God said, "'It is holy to you'" (Ex 31:14), "'a sign'" (:17), and a celebration of a "'personal covenant'" (:16). It is, "'That you may know that I am the Lord who sanctifies yoou'" (:12). It was so important that God used manna to institute a feast in the wilderness. They would eat it on a day they did not collect it because God said, "'Today is a sabbath to the Lord; today you will not find it in the field'" (Ex 16:25). "So the people rested on the seventh day" (:30). "'Everyone who profanes it will surely be put to death'" (31:14). "'Let no man go out of his place on the seventh day'" (16:29). "'It is a sabbath of complete rest'" (31:15). It is so "'They may see the bread that I fed you in the wilderness'" (16:22).
