Exodus 16:10-12

10While 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. 11The LORD said to Moses,

12“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.’ ”
