Exodus 16:22-24
16:22 And on the sixth day they gathered twice as much food, two omers per person; and all the leaders of the community came and told Moses.
16:23 He said to them, “This is what the Lord has said: ‘Tomorrow is a time of cessation from work, a holy Sabbath to the Lord. Whatever you want to bake, bake today; whatever you want to boil, boil today; whatever is left put aside for yourselves to be kept until morning.’”
16:24 So they put it aside until the morning, just as Moses had commanded, and it did not stink, nor were there any worms in it.
