Exodus 16:22-31 New Revised Standard Version (NRSV)
22 On the sixth day they gathered twice as much food, two omers apiece. When all the leaders of the congregation came and told Moses, 23 he said to them, “This is what the Lord has commanded: ‘Tomorrow is a day of solemn rest, a holy sabbath to the Lord; bake what you want to bake and boil what you want to boil, and all that is left over put aside to be kept until morning.’” 24 So they put it aside until morning, as Moses commanded them; and it did not become foul, and there were no worms in it. 25 Moses said, “Eat it today, for today is a sabbath to the Lord; today you will not find it in the field. 26 Six days you shall gather it; but on the seventh day, which is a sabbath, there will be none.”
27 On the seventh day some of the people went out to gather, and they found none. 28 The Lord said to Moses, “How long will you refuse to keep my commandments and instructions? 29 See! The Lord has given you the sabbath, therefore on the sixth day he gives you food for two days; each of you stay where you are; do not leave your place on the seventh day.” 30 So the people rested on the seventh day.
31 The house of Israel called it manna; it was like coriander seed, white, and the taste of it was like wafers made with honey.
