The last thing that G-d created in the story of creation was the Sabbath, the day of rest. The Sabbath is actually the seventh day of the week; it marks the ending of one week and the beginning of a new one. This is by no means the most important day of the week. The verses tell us that on the seventh day, G-d stopped His creation. This was a day after the male and female were created, as written in Genesis 2:1–3:
“And the heaven and the earth were finished, and all the host of them. And on the seventh day G-d finished His work which He had done; and He rested on the seventh day from all His work, which He had done. And G-d blessed the seventh day, and hallowed it; because in it He rested from all His work, which G-d had done in creation.”
Seemingly, there is no problem here. We have six days of work and one day of rest. However, if we look at Genesis 2:2, we learn that G-d finished His work on this day and not on the sixth day. This verse arose from a difficulty that caused changes in other versions of The Bible, for example, in The Septuagint (LXX) it is written that G-d finished His work on the sixth day and not on the seventh. Another way to solve this problem is with the interpretation of the verb finished (wayechal in Hebrew). This verb could denote the past tense, meaning that G-d had already finished creating on the sixth day.
