The heavens and the earth were finished, and all their vast array. On the seventh day God finished his work which he had made; and he rested on the seventh day from all his work which he had made. God blessed the seventh day, and made it holy, because he rested in it from all his work which he had created and made.
This is the history of the generations of the heavens and of the earth when they were created, in the day that Yahweh God made the earth and the heavens.
God spent six days working and one day resting. God didn’t intend for work on earth to go on and on without a weekend. He set aside one whole day for rest. God made a point of telling us that the weekend is His idea. Work is balanced with rest and reflection about the goodness of what has been done.
History: I am told by those who have carefully studied history that the last verse here is significant. I am told that it is an indicator that the part of the writing that came before it was witnessed and recorded by a single source. In this case, only “Yahweh God” is referenced. Many believe that Moses had access to very old stone writings that he copied into the Bible we have today by the inspiration of God. Perhaps, he got the words handed down from Adam himself who attributed them to God.
Science: God also made it clear that He completely finished His creating in six days. No more matter or energy is coming into the natural system. That’s exactly what scientists proved over years of experiments. This fact was made mathematically clear by Einstein and his famous work. One of the Laws of Thermodynamics tells us that no matter or energy is being created or destroyed.
