Then Moses made Israel set out from the Red Sea, and they went into the wilderness of Shur. They went three days in the wilderness and found no water. When they came to Marah, they could not drink the water of Marah because it was bitter; therefore it was named Marah. And the people grumbled against Moses, saying, “What shall we drink?” And he cried to the Lord, and the Lord showed him a log, and he threw it into the water, and the water became sweet.
There the Lord made for them a statute and a rule, and there he tested them, saying, “If you will diligently listen to the voice of the Lord your God, and do that which is right in his eyes, and give ear to his commandments and keep all his statutes, I will put none of the diseases on you that I put on the Egyptians, for I am the Lord, your healer.”
Then they came to Elim, where there were twelve springs of water and seventy palm trees, and they encamped there by the water.
They set out from Elim, and all the congregation of the people of Israel came to the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after they had departed from the land of Egypt. And the whole congregation of the people of Israel grumbled against Moses and Aaron in the wilderness, and the people of Israel said to them, “Would that we had died by the hand of the Lord in the land of Egypt, when we sat by the meat pots and ate bread to the full, for you have brought us out into this wilderness to kill this whole assembly with hunger.”
Then the Lord said to Moses, “Behold, I am about to rain bread from heaven for you, and the people shall go out and gather a day’s portion every day, that I may test them, whether they will walk in my law or not. On the sixth day, when they prepare what they bring in, it will be twice as much as they gather daily.” So Moses and Aaron said to all the people of Israel, “At evening you shall know that it was the Lord who brought you out of the land of Egypt, and in the morning you shall see the glory of the Lord, because he has heard your grumbling against the Lord. For what are we, that you grumble against us?” And Moses said, “When the Lord gives you in the evening meat to eat and in the morning bread to the full, because the Lord has heard your grumbling that you grumble against him—what are we? Your grumbling is not against us but against the Lord.”
Then Moses said to Aaron, “Say to the whole congregation of the people of Israel, ‘Come near before the Lord, for he has heard your grumbling.’” And as soon as Aaron spoke to the whole congregation of the people of Israel, they looked toward the wilderness, and behold, the glory of the Lord appeared in the cloud. And the Lord said to Moses, “I have heard the grumbling of the people of Israel. Say to them, ‘At twilight you shall eat meat, and in the morning you shall be filled with bread. Then you shall know that I am the Lord your God.’”
In the evening quail came up and covered the camp, and in the morning dew lay around the camp. And when the dew had gone up, there was on the face of the wilderness a fine, flake-like thing, fine as frost on the ground. When the people of Israel saw it, they said to one another, “What is it?” For they did not know what it was. And Moses said to them, “It is the bread that the Lord has given you to eat. This is what the Lord has commanded: ‘Gather of it, each one of you, as much as he can eat. You shall each take an omer, according to the number of the persons that each of you has in his tent.’” And the people of Israel did so. They gathered, some more, some less. But when they measured it with an omer, whoever gathered much had nothing left over, and whoever gathered little had no lack. Each of them gathered as much as he could eat. And Moses said to them, “Let no one leave any of it over till the morning.” But they did not listen to Moses. Some left part of it till the morning, and it bred worms and stank. And Moses was angry with them. Morning by morning they gathered it, each as much as he could eat; but when the sun grew hot, it melted.
On the sixth day they gathered twice as much bread, two omers each. And when all the leaders of the congregation came and told Moses, 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 will bake and boil what you will boil, and all that is left over lay aside to be kept till the morning.’” So they laid it aside till the morning, as Moses commanded them, and it did not stink, and there were no worms in it. Moses said, “Eat it 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, which is a Sabbath, there will be none.”
On the seventh day some of the people went out to gather, but they found none. And the Lord said to Moses, “How long will you refuse to keep my commandments and my laws? See! The Lord has given you the Sabbath; therefore on the sixth day he gives you bread for two days. Remain each of you in his place; let no one go out of his place on the seventh day.” So the people rested on the seventh day.
Now the house of Israel called its name manna. It was like coriander seed, white, and the taste of it was like wafers made with honey. Moses said, “This is what the Lord has commanded: ‘Let an omer of it be kept throughout your generations, so 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 jar, and put an omer of manna in it, and place it before the Lord to be kept throughout your generations.” As the Lord commanded Moses, so Aaron placed it before the testimony to be kept. The people of Israel ate the manna forty years, till they came to a habitable land. They ate the manna till they came to the border of the land of Canaan. (An omer is the tenth part of an ephah.)
All the congregation of the people of Israel moved on from the wilderness of Sin by stages, according to the commandment of the Lord, and camped at Rephidim, but there was no water for the people to drink. Therefore the people quarreled with Moses and said, “Give us water to drink.” And Moses said to them, “Why do you quarrel with me? Why do you test the Lord?” But the people thirsted there for water, and the people grumbled against Moses and said, “Why did you bring us up out of Egypt, to kill us and our children and our livestock with thirst?” So Moses cried to the Lord, “What shall I do with this people? They are almost ready to stone me.” And the Lord said to Moses, “Pass on before the people, taking with you some of the elders of Israel, and take in your hand the staff with which you struck the Nile, and go. Behold, I will stand before you there on the rock at Horeb, and you shall strike the rock, and water shall come out of it, and the people will drink.” And Moses did so, in the sight of the elders of Israel. And he called the name of the place Massah and Meribah, because of the quarreling of the people of Israel, and because they tested the Lord by saying, “Is the Lord among us or not?”
