What does Exodus 16:23 mean?

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.

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 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.

And he said, This is what the Lord has said, Tomorrow is a day of rest, a holy Sabbath to the Lord: what has to be cooked may be cooked; and what is over, put on one side to be kept till the morning.

And he saith unto them, `It <FI>is<Fi> that which Jehovah hath spoken <FI>of<Fi> ; a rest--a holy sabbath to Jehovah--<FI> is<Fi> to-morrow; that which ye bake, bake; and that which ye boil, boil; and all that is over, let rest for yourselves in charge till the morning.'

And he said to them: This is what the Lord hath spoken: To morrow is the rest of the sabbath sanctified to the Lord. Whatsoever work is to be done, do it; and the meats that are to be dressed, dress them; and whatsoever shall remain, lay it up until the morning.

And he said to them, This is what Jehovah has said: To-morrow is the rest, the holy sabbath, of Jehovah: bake what ye will bake, and cook what ye will cook; and lay up for yourselves all that remains over, to be kept for the morning.
