Exodus 16:6

3 And the children of Israel said to them, O that we had died by the hand of the LORD in the land of Egypt, when we sat by the flesh-pots, [and] when we did eat bread to the full: for ye have brought us forth into this wilderness, to kill this whole assembly with hunger.

4 Then said the LORD to Moses, Behold, I will rain bread from heaven for you; and the people shall go out and gather a certain rate every day, that I may prove them, whether they will walk in my law, or not.

5 And it shall come to pass, that on the sixth day they shall prepare [that] which they bring in; and it shall be twice as much as they gather daily.

6 And Moses and Aaron said to all the children of Israel, At evening, then ye shall know that the LORD hath brought you out from the land of Egypt:

7 And in the morning, then ye shall see the glory of the LORD; for that he heareth your murmurings against the LORD: And what [are] we, that ye murmur against us?

8 And Moses said, [This shall be] when the LORD shall give you in the evening flesh to eat, and in the morning bread to the full; for that the LORD heareth your murmurings which ye murmur against him: And what [are] we? your murmurings [are] not against us, but against the LORD.

9 And Moses spoke to Aaron, Say to all the congregation of the children of Israel, Come near before the LORD: for he hath heard your murmurings.
