RC 353.3
(Reflecting Christ 353.3)
Again and again He had manifested Himself to them. He had slain the firstborn of all the families in Egypt to accomplish their deliverance, and had brought them out of the land of their captivity with a high hand; He had fed them with angels’ food, and had covenanted to bring them into the Promised Land. But now, when difficulty rose before them, they broke into rebellion, distrusted God, and complained that Moses had brought them and their children out of Egypt only that they might die of thirst in the wilderness....
