Exodus 20:8-11
20:8 “Remember the Sabbath day to set it apart as holy.
20:9 For six days you may labor and do all your work,
20:10 but the seventh day is a Sabbath to the Lord your God; on it you shall not do any work, you, or your son, or your daughter, or your male servant, or your female servant, or your cattle, or the resident foreigner who is in your gates.
20:11 For in six days the Lord made the heavens and the earth and the sea and all that is in them, and he rested on the seventh day; therefore the Lord blessed the Sabbath day and set it apart as holy.
Exodus 34:21

Exodus 35:2
35:2 In six days
work may be done, but on the seventh day there must be a holy day
for you, a Sabbath of complete rest to the
Lord.
Anyone who does work on it will be put to death.
Isaiah 58:13
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.
Ezekiel 20:13
20:13 But the house of Israel rebelled against me in the wilderness; they did not follow my statutes and they rejected my regulations (the one who obeys them will live by them), and they utterly desecrated my Sabbaths. So I decided to pour out
my rage on them in the wilderness and destroy them.
