The Sign of the Sabbath

12 The LORD spoke to Moses, saying,
13 "But as for you, speak to the sons of Israel, saying, '1You shall surely observe My sabbaths; for this is 2a sign between Me and you throughout your generations, that you may know that I am the LORD who sanctifies you.
14 'Therefore you are to observe the sabbath, for it is holy to you. 3Everyone who profanes it shall surely be put to death; for whoever does any work on it, that person shall be cut off from among his people.
15 '4For six days work may be done, but on the seventh day there is a 5sabbath of complete rest, holy to the LORD; 6whoever does any work on the sabbath day shall surely be put to death.
16 'So the sons of Israel shall observe the sabbath, to celebrate the sabbath throughout their generations as a perpetual covenant.'
17 "7It is a sign between Me and the sons of Israel forever; 8for in six days the LORD made heaven and earth, but on the seventh day He ceased from labor, and was refreshed."
18 When He had finished speaking with him upon Mount Sinai, He gave Moses 9the two tablets of the testimony, tablets of stone, 10written by the finger of God.
