Exodus 16:22-23

On the sixth day, they gathered twice as much—two omers for each person—and the leaders of the community came and reported this to Moses. He said to them, “This is what the LORD commanded: ‘Tomorrow is to be a day of sabbath rest, a holy sabbath to the LORD. So bake what you want to bake and boil what you want to boil. Save whatever is left and keep it until morning.’ ”
