'Sabbath day' in the Bible

"Remember the Sabbath day, to keep it holy.

for in six days the LORD made heaven and earth, the sea, and all that is in them, and rested the seventh day; therefore the LORD blessed the Sabbath day, and made it holy.

Six days shall work be done, but on the seventh day is a Sabbath of solemn rest, holy to the LORD. Whoever does any work on the Sabbath day shall surely be put to death.

You shall kindle no fire throughout your habitations on the Sabbath day.'"
