Thematic Bible: What day the sabbath falls upon

[Earnestly] remember the Sabbath day, to keep it holy (withdrawn from common employment and dedicated to God). Six days you shall labor and do all your work, But the seventh day is a Sabbath to the Lord your God; in it you shall not do any work, you, or your son, your daughter, your manservant, your maidservant, your domestic animals, or the sojourner within your gates. read more.
For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. That is why the Lord blessed the Sabbath day and hallowed it [set it apart for His purposes].

Observe the Sabbath day to keep it holy, as the Lord your God commanded you. Six days you shall labor and do all your work, But the seventh day is a Sabbath to the Lord your God; in it you shall not do any work, you or your son or your daughter, or your manservant or your maidservant, or your ox or your donkey or any of your livestock, or the stranger or sojourner who is within your gates, that your manservant and your maidservant may rest as well as you. read more.
And [earnestly] remember that you were a servant in the land of Egypt and that the Lord your God brought you out from there with a mighty hand and an outstretched arm; therefore the Lord your God commanded you to observe and take heed to the Sabbath day.

The Lord said to Moses, Say to the Israelites, The set feasts or appointed seasons of the Lord which you shall proclaim as holy convocations, even My set feasts, are these: Six days shall work be done, but the seventh day is the Sabbath of rest, a holy convocation or assembly by summons. You shall do no work on that day; it is the Sabbath of the Lord in all your dwellings.

Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended His work which He had done; and He rested on the seventh day from all His work which He had done. And God blessed (spoke good of) the seventh day, set it apart as His own, and hallowed it, because on it God rested from all His work which He had created and done.
