'Sabbath day' in the Bible

“Remember the sabbath day, to keep it holy.

For in six days the Lord made the heavens and the 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.

For six days work may be done, but on the seventh day there is a sabbath of complete rest, holy to the Lord; whoever does any work on the sabbath day shall surely be put to death.

You shall not kindle a fire in any of your dwellings on the sabbath day.”
