Exodus 16:30

28The LORD said to Moses, “How long do you refuse to keep my commandments and my laws?

29Behold, because the LORD has given you the Sabbath, therefore he gives you on the sixth day the bread of two days. Everyone stay in his place. Let no one go out of his place on the seventh day.”

30So the people rested on the seventh day.

31The house of Israel called its name “Manna”, and it was like coriander seed, white; and its taste was like wafers with honey.

32Moses said, “This is the thing which the LORD has commanded, ‘Let an omer-full of it be kept throughout your generations, that they may see the bread with which I fed you in the wilderness, when I brought you out of the land of Egypt.’”
