Exodus 16:29

25Moses said, “Eat that today, for today is a Sabbath to the LORD. Today you shall not find it in the field.

26Six days you shall gather it, but on the seventh day is the Sabbath. In it there shall be none.”

27On the seventh day, some of the people went out to gather, and they found none.

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.’”

33Moses said to Aaron, “Take a pot, and put an omer-full of manna in it, and lay it up before the LORD, to be kept throughout your generations.”
