Exodus 16:4, 8

Then the LORD said to Moses, “Look, I’m going to rain down food from heaven for you. Each day the people can go out and pick up as much food as they need for that day. I will test them in this to see whether or not they will follow my instructions.

Then Moses added, “The LORD will give you meat to eat in the evening and bread to satisfy you in the morning, for he has heard all your complaints against him. What have we done? Yes, your complaints are against the LORD, not against us.”
