Exodus 16:2-3, 8

The whole congregation of the Israelites [grew discontented and] murmured and rebelled against Moses and Aaron in the wilderness, and the Israelites said to them, “Would that we had died by the hand of the LORD in the land of Egypt, when we sat by the pots of meat and ate bread until we were full; for you have brought us out into this wilderness to kill this entire assembly with hunger.”

Moses said, “This will happen when the LORD gives you meat to eat in the evening, and in the morning [enough] bread to be fully satisfied, because the LORD has heard your murmurings against Him; for what are we? Your murmurings are not against us, but against the LORD.”
