Exodus

And it came to pass, that on the sixth day they gathered twice as much bread, two omers for one man: and all the rulers of the congregation came and told Moses.

And he said unto them, This is that which the Lord hath said, To morrow is the rest of the holy sabbath unto the Lord: bake that which ye will bake to day, and seethe that ye will seethe; and that which remaineth over lay up for you to be kept until the morning.

And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you.

Six days shall work be done, but on the seventh day there shall be to you an holy day, a sabbath of rest to the Lord: whosoever doeth work therein shall be put to death.

Ye shall kindle no fire throughout your habitations upon the sabbath day.
