Exodus 16:9-18

9And Moses spoke to Aaron, Say to all the congregation of the children of Israel, Come near before the LORD: for he hath heard your murmurings. 10And it came to pass, as Aaron spoke to the whole congregation of the children of Israel, that they looked toward the wilderness, and, behold, the glory of the LORD appeared in the cloud. 11And the LORD spoke to Moses, saying, 12I have heard the murmurings of the children of Israel: speak to them, saying, At evening ye shall eat flesh, and in the morning ye shall be filled with bread; and ye shall know that I am the LORD your God.

13And it came to pass, that at evening the quails came up, and covered the camp: and in the morning the dew lay around the host. 14And when the dew that lay was gone up, behold, upon the face of the wilderness there lay a small round thing, as small as the hoar frost on the ground. 15And when the children of Israel saw it, they said one to another, It is manna: for they knew not what it was . And Moses said to them, This is the bread which the LORD hath given you to eat.1 16This is the thing which the LORD hath commanded, Gather of it every man according to his eating, an omer for every man, according to the number of your persons; take ye every man for them who are in his tents.23 17And the children of Israel did so, and gathered, some more, some less. 18And when they measured it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating.
