Exodus 16:27-31

Nevertheless, some of the people went out on the seventh day to gather it, but they found none. Then the LORD said to Moses, “How long will you refuse to keep my commands and my instructions? Bear in mind that the LORD has given you the Sabbath; that is why on the sixth day he gives you bread for two days. Everyone is to stay where they are on the seventh day; no one is to go out.” So the people rested on the seventh day. The people of Israel called the bread manna. It was white like coriander seed and tasted like wafers made with honey.
