Exodus 31:13

31:13 “Tell the Israelites, ‘Surely you must keep my Sabbaths, for it is a sign between me and you throughout your generations, that you may know that I am the Lord who sanctifies you.

Nehemiah 9:14

9:14 You made known to them your holy Sabbath; you issued commandments, statutes, and law to them through Moses your servant.

Isaiah 58:13-14

58:13 You must observe the Sabbath

rather than doing anything you please on my holy day.

You must look forward to the Sabbath

and treat the Lord’s holy day with respect.

You must treat it with respect by refraining from your normal activities,

and by refraining from your selfish pursuits and from making business deals.

58:14 Then you will find joy in your relationship to the Lord,

and I will give you great prosperity,

and cause crops to grow on the land I gave to your ancestor Jacob.”

Know for certain that the Lord has spoken.

Ezekiel 20:12

20:12 I also gave them my Sabbaths as a reminder of our relationship, so that they would know that I, the Lord, sanctify them.
