Exodus 31:14-17

14 You shall keep the Sabbath, because it is holy for you. Everyone who profanes it shall be put to death. a Whoever does any work on it, that soul shall be cut off from among his people. 15  b Six days shall work be done, but c the seventh day is a Sabbath of solemn rest, holy to the  Lord. d Whoever does any work on the Sabbath day shall be put to death. 16 Therefore the people of Israel shall keep the Sabbath, observing the Sabbath throughout their generations, as a covenant forever. 17  e It is a sign forever between me and the people of Israel that f in six days the  Lord made heaven and earth, and g on the seventh day he rested and was refreshed.’”
