Exodus 16:12-16

“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] This is what the LORD has commanded: ‘Let every man gather as much of it as he needs. Take an omer for each person, according to the number of people each of you has in his tent.’ ”
