Exodus 20:11

11For ain six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.

Exodus 31:13-17

13“You are to speak to the people of Israel and say, ‘Above all you shall keep my Sabbaths, for this is a sign between me and you throughout your generations, that you may know that I, the Lord, sanctify you. 14You shall keep the Sabbath, because it is holy for you. Everyone who profanes it shall be put to death. bWhoever does any work on it, that soul shall be cut off from among his people. 15 cSix days shall work be done, but dthe seventh day is a Sabbath of solemn rest, holy to the Lord. eWhoever does any work on the Sabbath day shall be put to death. 16Therefore the people of Israel shall keep the Sabbath, observing the Sabbath throughout their generations, as a covenant forever. 17 fIt is a sign forever between me and the people of Israel that gin six days the Lord made heaven and earth, and hon the seventh day he rested and was refreshed.’”

Nehemiah 13:15-22

15In those days I saw in Judah people treading winepresses ion the Sabbath, and bringing in heaps of grain and loading them on donkeys, and also wine, grapes, figs, and all kinds of loads, jwhich they brought into Jerusalem on the Sabbath day. And kI warned them on the day when they sold food. 16Tyrians also, who lived in the city, brought in fish and all kinds of goods and sold them on the Sabbath to the people of Judah, in Jerusalem itself! 17 lThen I confronted the nobles of Judah and said to them, “What is this evil thing that you are doing, mprofaning the Sabbath day? 18 nDid not your fathers act in this way, and did not our God bring all this disaster
The Hebrew word can mean evil, harm, or  disaster, depending on the context
on us and on this city? Now you are bringing more wrath on Israel by profaning the Sabbath.”

19As soon as it pbegan to grow dark at the gates of Jerusalem before the Sabbath, I commanded that the doors should be shut and gave orders that they should not be opened until after the Sabbath. And I stationed some of my servants at the gates, that no load might be brought in on the Sabbath day. 20Then the merchants and sellers of all kinds of wares lodged outside Jerusalem once or twice. 21 qBut I warned them and said to them, “Why do you lodge outside the wall? If you do so again, I will lay hands on you.” From that time on they did not come on the Sabbath. 22Then I commanded the Levites rthat they should purify themselves and come and guard the gates, to keep the Sabbath day holy. sRemember this also in my favor, O my God, and spare me according to the greatness of your steadfast love.

Isaiah 58:13

13 tIf you turn back your foot from the Sabbath,
from doing your pleasure
Or business
on my holy day,
and call the Sabbath a delight
and the holy day of the Lord honorable;
if you honor it, not going your own ways,
or seeking vyour own pleasure,
Or pursuing your own business
or talking idly;
Hebrew  or speaking a word

Ezekiel 20:12

12Moreover, I gave them ymy Sabbaths, as a sign between me and them, zthat they might know that I am the Lord who sanctifies them.

Ezekiel 44:24

24 aaIn a dispute, they shall act as judges, and they shall judge it according to my judgments. They shall keep my laws and my statutes in all my appointed feasts, and abthey shall keep my Sabbaths holy.
