Exodus 31:10-14

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,

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

And the LORD spake unto Moses, saying,

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.

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.
