Concerning Sabbath Day observance,

The Sinai Commandments (9 of the 10 Decalogue) are mere fragments of the spiritual law written upon the heart of human kind on Day-6; Commandment #4 is a civil edict given the children of Israel, exclusively. These nine moral laws were given Israel’s children by Elohim via Moses as guiding directives concerning their relationship with Elohim and their interpersonal relationships between the Tribes as they were embarking on a journey to the Promised Land that would entail encountering pagan tribes, pagan gods i.e., Baal, Molech, the deception of the demonic.

Sinai and Moses’ civil/ceremonial edicts were given to a specific group of chosen people, Jacob’s children, as these edicts were bulwarks against compromise with paganism, a compromise that would have thwarted Elohim’s objective of bringing forth His Messiah through Judah as prophesied.

Gentiles have never been obligated to observe a Sabbath regulation nor is there one example of a Gentile honoring a Sabbath; this, from Adam forward lest same was seeking inclusion in Israel’s theocracy subsequent Exodus 16 when Elohim commanded Sabbath observance via Moses, a directive given Jacob’s children, exclusively.

It is also interesting to note that Elohim was required to provide Moses exacting details as to how the Sabbath would be honored, why? Elohim provided Moses extensive details as to the Sabbath’s prohibitions due the truism that NO PRIOR PRECEDENT CONCERNING A SABBATH OBSERVANCE EXISTED.
