Exodus 16:27-31

On the seventh day some of the people went out to gather, but they found none. And the LORD said to Moses, “How long will you refuse to keep my commandments and my laws? See! The LORD has given you the Sabbath; therefore on the sixth day he gives you bread for two days. Remain each of you in his place; let no one go out of his place on the seventh day.” So the people rested on the seventh day. Now the house of Israel called its name manna. It was like coriander seed, white, and the taste of it was like wafers made with honey.
