Exodus 16:10, 12

So it happened that as Aaron spoke to the whole congregation of Israel, they looked toward the wilderness, and behold, the glory and brilliance of the LORD appeared in the cloud!

“I have heard the murmurings of the Israelites; speak to them, saying, ‘At twilight you shall eat meat, and in the morning you shall be filled with bread; and you shall know that I am the LORD your God.’ ”
