Exodus 16:23, 29

he said to them, “This is what the LORD commanded, because tomorrow is the Sabbath, the LORD’s holy day of rest. Bake what you want to bake, and boil what you want to boil today. Save the rest of the food until tomorrow morning.”

Look, the LORD has made the Sabbath a day of rest for you. So on the sixth day he will give you enough food for two days, but on the seventh day each of you must stay where you are. Do not go anywhere.”
