Exodus 16:22-23

On the sixth day they gathered twice as much bread, two omers each. And when all the leaders of the congregation came and told Moses, he said to them, “This is what the LORD has commanded: ‘Tomorrow is a day of solemn rest, a holy Sabbath to the LORD; bake what you will bake and boil what you will boil, and all that is left over lay aside to be kept till the morning.’”
