The Lord said to Moses, ²  31:13 “Tell the Israelites, ‘Surely you must keep my Sabbaths, ³  for it is a sign between me and you throughout your generations, that you may know that I am the Lord who sanctifies you. ⁴  31:14 So you must keep the Sabbath, for it is holy for you. Everyone who defiles it ⁵  must surely be put to death; indeed, ⁶  if anyone does ⁷  any ⁸  work on it, then that person will be cut off from among his ⁹  people. 31:15 Six days ¹⁰  work may be done, ¹¹  but on the seventh day is a Sabbath of complete rest, ¹²  holy to the Lord; anyone who does work on the Sabbath day must surely be put to death. 31:16 The Israelites must keep the Sabbath by observing the Sabbath throughout their generations as a perpetual covenant. 31:17 It is a sign between me and the Israelites forever; for in six days ¹³  the Lord made the heavens and the earth, and on the seventh day he rested and was refreshed.’” ¹⁴
