Exodus 16:20-24

20However, they did not listen to Moses. Some of them preserved it until the morning—but it bred worms and rotted. So Moses was angry with them.

21So they gathered it morning by morning, each man according to his needs, and as the sun became hot it melted.

22On the sixth day they gathered twice as much bread, two omers for each individual. So all the leaders of the community came and informed Moses.

23But he said to them, “This is what Adonai has said. Tomorrow is a Shabbat rest, a holy Shabbat to Adonai. Bake whatever you would bake, and boil what you would boil. Store up for yourselves everything that remains, to be kept until the morning.”

24So they set it aside until the morning, just as Moses instructed, and it did not rot nor were there any worms.
