Exodus 16:21-23

After this the people gathered the food morning by morning, each family according to its need. And as the sun became hot, the flakes they had not picked up melted and disappeared. On the sixth day, they gathered twice as much as usual—four quarts for each person instead of two. Then all the leaders of the community came and asked Moses for an explanation. 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.”
