12. And the Lord spoke further unto Moses, saying,
13. And thou shalt speak unto the sons of Israel, saying, With all this ye shall keep my sabbaths; for it is a sign between me and you throughout your ages; 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; those that defile it shall surely be put to death; for whoever does any work therein, that soul shall be cut off from among his people.
15. Six days shall work be done; but the seventh, the sabbath of rest, shall be holy to the Lord; whoever does any work in the sabbath day shall surely be put to death.
16. Therefore the sons of Israel shall keep the sabbath, to observe the sabbath throughout their ages for a perpetual covenant.
