'On the Sabbath' in the Bible

Therefore, you shall keep the Sabbath, for it is holy to you. Everyone who profanes it must be put to death; for whoever does work on the Sabbath, that person (soul) shall be cut off from among his people [excluding him from the atonement made for them].

Six days shall work be done, but on the seventh day is a sabbath of solemn rest, holy to Jehovah: whosoever doeth any work on the sabbath day, he shall surely be put to death.

“You shall work for six days, but on the seventh day you shall rest; [even] in plowing time and in harvest you shall rest [on the Sabbath].

Ye shall kindle no fire throughout your habitations upon the sabbath day.
