Exodus 16:23 ASV

²¹  And they gathered it morning by morning, every man according to his eating: and when the sun waxed hot, it melted.

²²  And it came to pass, that on the sixth day they gathered twice as much bread, two omers for each one: and all the rulers of the congregation came and told Moses.

²³  And he said unto them, This is that which Jehovah hath spoken, Tomorrow 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.

²⁴  And they laid it up till the morning, as Moses bade: and it did not become foul, neither was there any worm therein.

²⁵  And Moses said, Eat that to-day; for to-day is a sabbath unto Jehovah: to-day ye shall not find it in the field.
