By the seventh day God completed His work that He had done, and He rested on the seventh day from all His work that He had done. God blessed the seventh day and declared it holy, for on it He rested from His work of creation.

For the Lord made the heavens and the earth, the sea, and everything in them in six days; then He rested on the seventh day. Therefore the Lord blessed the Sabbath day and declared it holy.

It is a sign forever between Me and the Israelites, for in six days the Lord made the heavens and the earth, but on the seventh day He rested and was refreshed.”

for somewhere He has spoken about the seventh day in this way:

And on the seventh day
God rested from all His works.

He told them, “This is what the Lord has said: ‘Tomorrow is a day of complete rest, a holy Sabbath to the Lord. Bake what you want to bake, and boil what you want to boil, and set aside everything left over to be kept until morning.’”

Work may be done for six days, but on the seventh day there must be a Sabbath of complete rest, dedicated to the Lord. Anyone who does work on the Sabbath day must be put to death.

For six days work is to be done, but on the seventh day you are to have a holy day, a Sabbath of complete rest to the Lord. Anyone who does work on it must be executed. Do not light a fire in any of your homes on the Sabbath day.”

So the people rested on the seventh day.

“You are to labor six days but you must rest on the seventh day; you must even rest during plowing and harvesting times.

“Work may be done for six days, but on the seventh day there must be a Sabbath of complete rest, a sacred assembly. You are not to do any work; it is a Sabbath to the Lord wherever you live.

but the seventh day is a Sabbath to the Lord your God. You must not do any work—you, your son or daughter, your male or female slave, your livestock, or the foreigner who is within your gates.

“Do your work for six days but rest on the seventh day so that your ox and your donkey may rest, and the son of your female slave as well as the foreign resident may be refreshed.

“On the Sabbath day present two unblemished year-old male lambs, four quarts of fine flour mixed with oil as a grain offering, and its drink offering.

It is the burnt offering for every Sabbath, in addition to the regular burnt offering and its drink offering.

You revealed Your holy Sabbath to them,
and gave them commands, statutes, and instruction
through Your servant Moses.

I also gave them My Sabbaths to serve as a sign between Me and them, so they will know that I am Yahweh who sets them apart as holy.

Keep My Sabbaths holy, and they will be a sign between Me and you, so you may know that I am Yahweh your God.

“Tell the Israelites: In the seventh month, on the first day of the month, you are to have a day of complete rest, commemoration, and joyful shouting—a sacred assembly.

It is a Sabbath of complete rest for you, and you must practice self-denial; it is a permanent statute.

It will be a Sabbath of complete rest for you, and you must practice self-denial. You are to observe your Sabbath from the evening of the ninth day of the month until the following evening.”

“You are to celebrate the Lord’s festival on the fifteenth day of the seventh month for seven days after you have gathered the produce of the land. There will be complete rest on the first day and complete rest on the eighth day.

These are in addition to the offerings for the Lord’s Sabbaths, your gifts, all your vow offerings, and all your freewill offerings that you give to the Lord.
