Exodus 16:29-31

New Century Version

²⁹ 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.” ³⁰ So the people rested on the seventh day.

³¹ The people of Israel called the food manna. It was like small white seeds and tasted like wafers made with honey.
