Exodus 16:14-20

When the dew evaporated, a flaky substance as fine as frost blanketed the ground. The Israelites were puzzled when they saw it. “What is it?” they asked each other. They had no idea what it was. And Moses told them, “It is the food the LORD has given you to eat. These are the LORD’s instructions: Each household should gather as much as it needs. Pick up two quarts for each person in your tent.” So the people of Israel did as they were told. Some gathered a lot, some only a little. But when they measured it out, everyone had just enough. Those who gathered a lot had nothing left over, and those who gathered only a little had enough. Each family had just what it needed. Then Moses told them, “Do not keep any of it until morning.” But some of them didn’t listen and kept some of it until morning. But by then it was full of maggots and had a terrible smell. Moses was very angry with them.
