Exodus Chapter 31 Webster's Bible
And I, behold, I have given with him Aholiab the son of Ahisamach of the tribe of Dan; and in the hearts of all that are wise-hearted I have put wisdom; that they may make all that I have commanded thee:
Speak thou also to 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 to you. Every one that profaneth it shall surely be put to death: for whoever doeth any work therein, that soul shall be cut off from among his people.
