TSK · Numbers 15:32

And he said unto them, This is that which Jehovah hath spoken, To-morrow is a solemn rest, a holy sabbath unto Jehovah: bake that which ye will bake, and boil that which ye will boil; and all that remaineth over lay up for you to be kept until the morning.

Remember the sabbath day, to keep it holy.

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