Exodus 31:13-15

21st Century King James Version

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 who doth sanctify you.

¹⁴ Ye shall keep the Sabbath therefore, for it is holy unto you. Every one who 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 on the seventh is the Sabbath of rest, holy to the Lord. Whosoever doeth any work on the Sabbath day, he shall surely be put to death.
