14Therefore you are to keep the Sabbath, for it is holy to you. Everyone who profanes it must be put to death; for whoever does any work on it, that person shall be cut off from among his people. 15For six days work may be done, but on the seventh day there is a Sabbath of complete rest, holy to the Lord; whoever does any work on the Sabbath day must be put to death.
