Exodus 16:22-26

²²Now on the sixth day they gathered twice as much bread, two omers for each one. When all the leaders of the congregation came and told Moses, ²³then he said to them, "This is what the Lord meant: Tomorrow is a sabbath observance, a holy sabbath to the Lord. Bake what you will bake and boil what you will boil, and all that is left over put aside to be kept until morning." ²⁴So they put it aside until morning, as Moses had ordered, and it did not become foul nor was there any worm in it. ²⁵Moses said, "Eat it today, for today is a sabbath to the Lord; today you will not find it in the field. ²⁶Six days you shall gather it, but on the seventh day, the sabbath, there will be none."
