Exodus: Looking Back-Heading Forward

The whole Israelite community set out from Elim and came to the Desert of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after they had come out of Egypt. In the desert the whole community grumbled against Moses and Aaron. The Israelites said to them, “If only we had died by the Lord’s hand in Egypt! There we sat around pots of meat and ate all the food we wanted, but you have brought us out into this desert to starve this entire assembly to death.”
Then the Lordsaid to Moses, “I will rain down bread from heaven for you. The people are to go out each day and gather enough for that day. In this way I will test them and see whether they will follow my instructions. On the sixth day they are to prepare what they bring in, and that is to be twice as much as they gather on the other days.”
So Moses and Aaron said to all the Israelites, “In the evening you will know that it was the Lordwho brought you out of Egypt, and in the morning you will see the glory of the Lord, because he has heard your grumbling against him. Who are we, that you should grumble against us?” Moses also said, “You will know that it was the Lordwhen he gives you meat to eat in the evening and all the bread you want in the morning, because he has heard your grumbling against him. Who are we? You are not grumbling against us, but against the Lord.”
Then Moses told Aaron, “Say to the entire Israelite community, ‘Come before the Lord, for he has heard your grumbling.’ ”
While Aaron was speaking to the whole Israelite community, they looked toward the desert, and there was the glory of the Lordappearing in the cloud.
The Lordsaid to Moses, “I have heard the grumbling of the Israelites. Tell them, ‘At twilight you will eat meat, and in the morning you will be filled with bread. Then you will know that I am the Lordyour God.’ ”
That evening quail came and covered the camp, and in the morning there was a layer of dew around the camp. When the dew was gone, thin flakes like frost on the ground appeared on the desert floor. When the Israelites saw it, they said to each other, “What is it?” For they did not know what it was.
Moses said to them, “It is the bread the Lordhas given you to eat. This is what the Lordhas commanded: ‘Everyone is to gather as much as they need. Take an omerfor each person you have in your tent.’ ”
The Israelites did as they were told; some gathered much, some little. And when they measured it by the omer, the one who gathered much did not have too much, and the one who gathered little did not have too little. Everyone had gathered just as much as they needed.
