Exodus 16:23-24

He told them, “This is what the LORD commanded: Tomorrow will be a day of complete rest, a holy Sabbath day set apart for the LORD. So bake or boil as much as you want today, and set aside what is left for tomorrow.” So they put some aside until morning, just as Moses had commanded. And in the morning the leftover food was wholesome and good, without maggots or odor.
