Exodus 16:20

18When they measured it with an omer, he who gathered much had nothing over, and he who gathered little had no lack. They each gathered according to his eating.

19Moses said to them, “Let no one leave of it until the morning.”

20Notwithstanding they didn’t listen to Moses, but some of them left of it until the morning, so it bred worms and became foul; and Moses was angry with them.

21They gathered it morning by morning, everyone according to his eating. When the sun grew hot, it melted.

22On 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.
