Exodus 31:12

9 And the altar of burnt offering with all his furniture, and the laver and his foot,

10 And the cloths of service, and the holy garments for Aaron the priest, and the garments of his sons, to minister in the priest’s office,

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

12 And the LORD spake unto Moses, saying,

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

14 Ye shall keep the sabbath therefore; for it [is] holy unto you: every one that defileth 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 may work be done; but in the seventh [is] the sabbath of rest, holy to the LORD: whosoever doeth [any] work in the sabbath day, he shall surely be put to death.
