Exodus 16:9-15

Then Moses said to Aaron, “Announce this to the entire community of Israel: ‘Present yourselves before the LORD, for he has heard your complaining.’” And as Aaron spoke to the whole community of Israel, they looked out toward the wilderness. There they could see the awesome glory of the LORD in the cloud. Then the LORD said to Moses, “I have heard the Israelites’ complaints. Now tell them, ‘In the evening you will have meat to eat, and in the morning you will have all the bread you want. Then you will know that I am the LORD your God.’” That evening vast numbers of quail flew in and covered the camp. And the next morning the area around the camp was wet with dew.

And Moses told them, “It is the food the LORD has given you to eat.
