Exodus 16:8, 12-13

And Moses said, “When the LORD gives you in the evening meat to eat and in the morning bread to the full, because the LORD has heard your grumbling that you grumble against him—what are we? Your grumbling is not against us but against the LORD.”

“I have heard the grumbling of the people of Israel. Say to them, ‘At twilight you shall eat meat, and in the morning you shall be filled with bread. Then you shall know that I am the LORD your God.’” In the evening quail came up and covered the camp, and in the morning dew lay around the camp.
