Exodus 16:1-25 NKJV
And they journeyed from Elim, and all the congregation of the children of Israel came to the Wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after they departed from the land of Egypt. Then the whole congregation of the children of Israel complained against Moses and Aaron in the wilderness. And the children of Israel said to them, “Oh, that we had died by the hand of the LORD in the land of Egypt, when we sat by the pots of meat and when we 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 will rain bread from heaven for you. And the people shall go out and gather a certain quota every day, that I may test them, whether they will walk in My law or not. And it shall be on the sixth day that they shall prepare what they bring in, and it shall be twice as much as they gather daily.”
Then Moses and Aaron said to all the children of Israel, “At evening you shall know that the LORD has brought you out of the land of Egypt. And in the morning you shall see the glory of the LORD; for He hears your complaints against the LORD. But what are we, that you complain against us?” Also Moses said, “This shall be seen when the LORD gives you meat to eat in the evening, and in the morning bread to the full; for the LORD hears your complaints which you make against Him. And what are we? Your complaints are not against us but against the LORD.”
Then Moses spoke to Aaron, “Say to all the congregation of the children of Israel, ‘Come near before the LORD, for He has heard your complaints.’ ” Now it came to pass, as Aaron spoke to the whole congregation of the children of Israel, that they looked toward the wilderness, and behold, the glory of the LORD appeared in the cloud.
And the LORD spoke to Moses, saying, “I have heard the complaints of the children of Israel. Speak to them, saying, ‘At twilight you shall eat meat, and in the morning you shall be filled with bread. And you shall know that I am the LORD your God.’ ”
So it was that quails came up at evening and covered the camp, and in the morning the dew lay all around the camp. And when the layer of dew lifted, there, on the surface of the wilderness, was a small round substance, as fine as frost on the ground. So when the children 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, “This is the bread which the LORD has given you to eat. This is the thing which the LORD has commanded: ‘Let every man gather it according to each one’s need, one omer for each person, according to the number of persons; let every man take for those who are in his tent.’ ”
Then the children of Israel did so and gathered, some more, some less. So when they measured it by omers, he who gathered much had nothing left over, and he who gathered little had no lack. Every man had gathered according to each one’s need. And Moses said, “Let no one leave any of it till morning.” Notwithstanding they did not heed Moses. But some of them left part of it until morning, and it bred worms and stank. And Moses was angry with them. So they gathered it every morning, every man according to his need. And when the sun became hot, it melted.
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.
