seventh is the sabbath
Exodus 31:15
31:15 seventh is the sabbath. Breaking God’s rest day was defined by Him as a capital crime among His chosen people, and this at least shows all people how vital its observance is to Him. As far as Israel was concerned, it was to be observed perpetually. Since its use long antedates the calling of Israel, it should actually be regarded as a perpetual reminder to all people of the preeminent importance God placed on the fact of His completed work of creation, and His abhorrence of any religion (e.g., evolutionism) or any practice which denied or trivialized this foundational doctrine.
