Exodus 16:20-24

Notwithstanding they did not heed Moses. But some of them left part of it until morning, and it bred worms and stank. And Moses was angry with them. So they gathered it every morning, every man according to his need. And when the sun became hot, it melted. And so it was, on the sixth day, that they gathered twice as much bread, two omers for each one. And all the rulers of the congregation came and told Moses. Then 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.’ ” So they laid it up till morning, as Moses commanded; and it did not stink, nor were there any worms in it.
