Exodus 31:13 ASV

¹¹  and the anointing oil, and the incense of sweet spices for the holy place: according to all that I have commanded thee shall they do.

¹²  And Jehovah spake unto Moses, saying,

¹³  Speak thou also unto the children of Israel, saying, Verily ye shall keep my sabbaths: for it is a sign between me and you throughout your generations; that ye may know that I am Jehovah who sanctifieth you.

¹⁴  Ye shall keep the sabbath therefore; for it is holy unto you: every one that profaneth it shall surely be put to death; for whosoever doeth any work therein, that soul shall be cut off from among his people.

¹⁵  Six days shall work be done, but on the seventh day is a sabbath of solemn rest, holy to Jehovah: whosoever doeth any work on the sabbath day, he shall surely be put to death.
