Exodus 16:4, 8

Then the LORD said to Moses, “Behold, I am about to rain bread from heaven for you, and the people shall go out and gather a day’s portion every day, that I may test them, whether they will walk in my law or not.

And Moses said, “When the LORD gives you in the evening meat to eat and in the morning bread to the full, because the LORD has heard your grumbling that you grumble against him—what are we? Your grumbling is not against us but against the LORD.”
