1. Genesis 1:31 “And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day. 2:1 Thus the heavens and the earth were finished, and all the host of them. 2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. 3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.” https://www.bible.com/bible/1/GEN.1.KJV https://www.bible.com/bible/1/GEN.2.KJV God instituted the Sabbath at creation; there were no Jewish people in Eden.
2. Exodus 20:8 “Remember the sabbath day, to keep it holy. 9 Six days shalt thou labour, and do all thy work: 10 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 manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: 11 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.” https://www.bible.com/bible/1/EXO.20.KJV Why did God start this commandment with the word “remember”? The Sabbath is a memorial of God creating the earth in six days and resting on the seventh.
