Exodus 16:3-7

3And 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.”

4Then 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.

5And 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.”

6Then 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.

7And 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?”
