Exodus 16:27-31

Yet it came about on the seventh day that some of the people went out to gather, but they found none.

Then the Lord said to Moses, “How long do you refuse to keep My commandments and My instructions?

See, the Lord has given you the Sabbath; for that reason He gives you bread for two days on the sixth day. Remain, everyone, in his place; no one is to leave his place on the seventh day.”

So the people rested on the seventh day.

And the house of Israel named the bread manna, and it was like coriander seed, white, and its taste was like wafers with honey.
