From the very beginning, God is introduced as One who is working:
He created all that is known about life in six days (Gen 1:1-31).
Thus the heavens and the earth were completed, and all their hosts. By the seventh day God completed His work
which He had done, and He rested on the seventh day from all His work which He had done. Then God blessed the seventh day and sanctified
it, because in it He rested from all His work which God had created and made. (Gen 2:1-3)
Here, in comparison to other pagan creation accounts, an important distinction must be made. While the Hebrew term "elōhîm" can be
used to refer to pagan gods, God calls Himself "Yĕhovah 'elōhîm" (Lord God).
This is the account of the heavens and the earth when they were created, in the day that the Lord
(Yĕhovah) God ('elōhîm) made earth and heaven. (Gen 2:4)
By including His "memorial name to all generations" (Ex 3:15), YHWH,
God is making a distinction that only the God who truly exists accomplished Creation.
