Exodus 16:7

4 Then the LORD said to Moses, “Behold, I will rain bread from the sky for you, and the people shall go out and gather a day’s portion every day, that I may test them, whether they will walk in my law or not.

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

6 Moses and Aaron said to all the children of Israel, “At evening, you shall know that the LORD has brought you out from the land of Egypt.

7 In the morning, you shall see the LORD’s glory; because he hears your murmurings against the LORD. Who are we, that you murmur against us?”

8 Moses said, “Now the LORD will give you meat to eat in the evening, and in the morning bread to satisfy you, because the LORD hears your murmurings which you murmur against him. And who are we? Your murmurings are not against us, but against the LORD.”

9 Moses said to Aaron, “Tell all the congregation of the children of Israel, ‘Come close to the LORD, for he has heard your murmurings.’”

10 As Aaron spoke to the whole congregation of the children of Israel, they looked toward the wilderness, and behold, the LORD’s glory appeared in the cloud.
