Exodus 16:28

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

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

27 It happened on the seventh day, that some of the people went out to gather, and they found none.

28 Yahweh said to Moses, "How long do you refuse to keep my commandments and my laws?

29 Behold, because Yahweh 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."

30 So the people rested on the seventh day.

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