Exodus 16:9-15

Then Moses said to Aaron, “Say to all the congregation of Israel, ‘Approach the LORD, because He has heard your murmurings.’ ” So it happened that as Aaron spoke to the whole congregation of Israel, they looked toward the wilderness, and behold, the glory and brilliance of the LORD appeared in the cloud! Then the LORD spoke to Moses, saying, “I have heard the murmurings of the Israelites; speak to them, saying, ‘At twilight you shall eat meat, and in the morning you shall be filled with bread; and you shall know that I am the LORD your God.’ ” So in the evening the quails came up and covered the camp, and in the morning there was a blanket of dew around the camp. When the layer of dew evaporated, on the surface of the wilderness there was a fine, flake-like thing, as fine as frost on the ground. When the Israelites saw it, they said to one another, “What is it?” For they did not know what it was. And Moses said to them, “This is the bread which the LORD has given you to eat. [John 6:31, 33]
