Exodus 16:9-15

Then Moses told Aaron, “Say to the entire Israelite community, ‘Come before the LORD, for he has heard your grumbling.’ ” While Aaron was speaking to the whole Israelite community, they looked toward the desert, and there was the glory of the LORD appearing in the cloud. The LORD said to Moses, “I have heard the grumbling of the Israelites. Tell them, ‘At twilight you will eat meat, and in the morning you will be filled with bread. Then you will know that I am the LORD your God.’ ” That evening quail came and covered the camp, and in the morning there was a layer of dew around the camp. When the dew was gone, thin flakes like frost on the ground appeared on the desert floor. When the Israelites saw it, they said to each other, “What is it?” For they did not know what it was. Moses said to them, “It is the bread the LORD has given you to eat.
