Exodus 16 : 1-5, 9-15
The Israelites left Elim and the entire community reached the desert of Sin, between Elim and Sinai, on the fifteenth day of the second month after leaving Egypt. In the desert the whole community of Israel grumbled against Moses and Aaron and said to them, “If only we had died by the hand of YHVH in Egypt when we sat down to caldrons of meat and ate all the bread we wanted, whereas you have brought us to this desert to let the whole assembly die of starvation!”
YHVH then said to Moses, “Now I am going to rain down bread from heaven for you. Each day the people are to gather what is needed for that day. In this way I will test them to see if they will follow My teaching or not. On the sixth day when they prepare when they have brought in, they will find that there is twice as much as they gather each day.”
Then Moses directed Aaron to say to the whole community of Israel, “Draw near to YHVH for He has heard your complaints.” It happened that as Aaron was speaking to the full assembly of Israel, they turned towards the desert and saw the Glory of YHVH in the midst of the cloud.
Then YHVH spoke to Moses, “I have heard the complaints of Israel. Speak to them and say : ‘Between the two evenings you will eat meat, and in the morning you will have bread to your heart’s content; then you shall know that I am YHVH, your God!”
In the evening quails came up and covered the camp. And in the morning, dew had fallen around the camp. When the dew lifted , there was on the surface of the desert a thin crust like hoarfrost. The people of Israel upon seeing it said to one another, “What is it?” for they did not know what it was. Moses told them, “It is the bread that YHVH has given you to eat.”
