"The lack of the evening and morning refrain at the end of this day
signifies the seventh day apart and
emphasizes its holiness.
Indeed, the term ‘the seventh day’ occurs three
times in Genesis 2:2–3
to denote three activities of God.
Firstly, God completed His work on
the seventh day.
Secondly, God rested on the seventh day.
Finally, God
blessed the seventh day and declared it to be holy because on that day
He ceased His creative work.
...God did not
cease all work, only His creative work."
