Leviticus 23:1-3 The Lord said to Moses: 2 Speak to the Israelites and say to them: These are my appointed times, the Lord’s appointed times, which you will declare to be holy occasions: 3 Work can be done for six days, but the seventh day is a Sabbath of special rest, a holy occasion. You must not do any work on it; wherever you live, it is a Sabbath to the Lord.

Moses was insisted upon in the name of God. Perhaps. He then insisted upon the Israelites, establishing certain festivals as sacred assemblies. At this time the seventh day was established as a holy sabbatical, a consecrated day of rest and renewal, a time to revitalize connection with the Divine, Mystery, Spirit, God, Higher Power, Other, Sacred dimension of life. Let it be so!
