some insight on the translation of rest:
While it is true that many translations of the Bible such as the New Revised Version Standard (NRSV), the King James' Version (KJV) and others render the word Shavat as "rested" a more accurate translation of Shavat is "abstained," i.e., "God blessed the seventh day and sanctified it because He abstained from all His work which God created to make" (Gen. 2:4). Nachmanides (12th century) interpreted these words to mean "he ceased to perform all His creative work."
