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.” ’
