Ellicott's commentary: "lifeless manna fell and lay upon the ground until they gathered it, and passed to corruption if they did not. Each day's supply met the need of each day, but met that only. He is the bread containing life in Himself, coming by His own will and act from heaven, living among men, imparting life to those who eat by coming to and believing on Him, so that it becomes in them a principle of life, too, which cannot die, but shall live for ever"
