14Keep the Sabbath, for it is holy to you. Anyone who profanes it must surely be put to death. Whoever does any work on that day must be cut off from among his people.
15For six days work may be done, but the seventh day is a Sabbath of complete rest, holy to the LORD. Whoever does any work on the Sabbath day must surely be put to death.
— Exodus 31:14-15
