'Sabbath day' in the Bible

"Remember the Sabbath day that thou sanctify it.

For in six days the LORD made both heaven and earth and the sea and all that in them is and rested the seventh day: wherefore the LORD blessed the Sabbath day and hallowed it.

Six days shall men work, but the seventh day is the Sabbath of the holy rest of the LORD: so that whosoever doeth any work in the Sabbath day, shall die for it.

Moreover, ye shall kindle no fire throughout all your habitations upon the Sabbath day."
