Exodus 16:23-25

23Then he said to them, “This is what the Lord has said: ‘Tomorrow is a Sabbath rest, a holy Sabbath to the Lord. Bake what you will bake today, and boil what you will boil; and lay up for yourselves all that remains, to be kept until morning.’ ”

24So they laid it up till morning, as Moses commanded; and it did not stink, nor were there any worms in it.

25Then Moses said, “Eat that today, for today is a Sabbath to the Lord; today you will not find it in the field.
