Exodus 16:16-21

16This is what the Lord has commanded: ‘Gather of it, each one of you, as much as he can eat. You shall each take an aomer,
An  omer was about 2 quarts or 2 liters
according to the number of the persons that each of you has in his tent.’”
17And the people of Israel did so. They gathered, some more, some less. 18But when they measured it with an omer, cwhoever gathered much had nothing left over, and whoever gathered little had no lack. Each of them gathered as much as he could eat. 19And Moses said to them, “Let no one leave any of it over till the morning.” 20But they did not listen to Moses. Some left part of it till the morning, and dit bred worms and stank. And Moses was angry with them. 21Morning by morning they gathered it, each as much as he could eat; but when the sun grew hot, it melted.
