Exodus 16:9-15

Then Moses said to Aaron, “Speak to the whole community of the Israelites, and say to them, ‘Meet together in the presence of the LORD, because he has heard your grumblings.’ ” While Aaron was speaking to the whole community of the Israelites, they looked toward the desert. There the glory of the LORD appeared in a cloud. The LORD said to Moses, “I have heard the grumblings of the people of Israel. So tell them, ‘At twilight you will eat meat, and every morning you will eat all the bread you want. Then you will know I am the LORD your God.’ ” That evening quail came and covered the camp, and in the morning dew lay around the camp. When the dew was gone, thin flakes like frost were on the desert ground. When the Israelites saw it, they asked each other, “What is it?” because they did not know what it was. So Moses told them, “This is the bread the LORD has given you to eat.
