'Sabbath day' in the Bible

Remember the Sabbath day, to keep it holy.

For in six days Jehovah made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore Jehovah blessed the Sabbath day, and sanctified it.

Six days may work be done, but on the seventh is the sabbath of rest, holy to Jehovah. Whoever does any work in the Sabbath day, he shall surely be put to death.

You shall kindle no fire throughout your living places upon the Sabbath day.
