Exodus 31:13

10 And the robes of needlework, the holy robes for Aaron and for his sons, for their use when acting as priests,

11 And the holy oil, and the perfume of sweet spices for the holy place; they will do whatever I have given you orders to have done.

12 And the Lord said to Moses,

13 Say to the children of Israel that they are to keep my Sabbaths; for the Sabbath day is a sign between me and you through all your generations; so that you may see that I am the Lord who makes you holy.

14 So you are to keep the Sabbath as a holy day; and anyone not honouring it will certainly be put to death: whoever does any work on that day will be cut off from his people.

15 Six days may work be done, but the seventh day is a Sabbath of complete rest, holy to the Lord; whoever does any work on the Sabbath day is to be put to death.

16 And the children of Israel are to keep the Sabbath holy, from generation to generation, by an eternal agreement.
