“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, Tomorrow is the rest of the holy Sabbath unto the Lord. Bake that which ye will bake today, and seethe that ye will seethe; and that which remaineth over, lay up for you, to be kept until the morning. And they laid it up till the morning, as Moses bade; and it did not stink, neither was there any worm therein. And Moses said, Eat that today; for today is a Sabbath unto the Lord. Today ye shall not find it in the field. Six days ye shall gather it; but on the seventh day, which is the Sabbath, in it there shall be none.”
The Lord is no less particular now in regard to his Sabbath, than when he gave the foregoing special directions to the children of Israel.
