Exodus 16:13-18

13In the evening the quail came up and covered the camp, and in the morning a layer of dew was all around the camp.

14When the layer of dew had evaporated, there on the surface of the desert was a thin flaky substance, thin like frost on the earth.

15When the Israelites saw it, they said to one another, “What is it?” because they did not know what it was. Moses said to them, “It is the bread that the Lord has given you for food.

16“This is what the Lord has commanded: ‘Each person is to gather from it what he can eat, an omer per person according to the number of your people; each one will pick it up for whoever lives in his tent.’”

17The Israelites did so, and they gathered – some more, some less.

18When they measured with an omer, the one who gathered much had nothing left over, and the one who gathered little lacked nothing; each one had gathered what he could eat.
