Exodus 16:22-35 NKJV
And so it was, on the sixth day, that they gathered twice as much bread, two omers for each one. And all the rulers of the congregation came and told Moses. Then he said to them, “This is what the LORD has said: ‘Tomorrow is a Sabbath rest, a holy Sabbath to the LORD. Bake what you will bake today, and boil what you will boil; and lay up for yourselves all that remains, to be kept until morning.’ ” So they laid it up till morning, as Moses commanded; and it did not stink, nor were there any worms in it. Then Moses said, “Eat that today, for today is a Sabbath to the LORD; today you will not find it in the field. Six days you shall gather it, but on the seventh day, the Sabbath, there will be none.”
Now it happened that some of the people went out on the seventh day to gather, but they found none. And the LORD said to Moses, “How long do you refuse to keep My commandments and My laws? See! For the LORD has given you the Sabbath; therefore He gives you on the sixth day bread for two days. Let every man remain in his place; let no man go out of his place on the seventh day.” So the people rested on the seventh day.
And the house of Israel called its name Manna. And it was like white coriander seed, and the taste of it was like wafers made with honey.
Then Moses said, “This is the thing which the LORD has commanded: ‘Fill an omer with it, to be kept for 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.’ ” And Moses said to Aaron, “Take a pot and put an omer of manna in it, and lay it up before the LORD, to be kept for your generations.” As the LORD commanded Moses, so Aaron laid it up before the Testimony, to be kept. And the children of Israel ate manna forty years, until they came to an inhabited land; they ate manna until they came to the border of the land of Canaan.
