John 6:34,35 - Joseph Benson’s Commentary on the Old and New Testaments

Then said they, Evermore give us this bread On which it seems our life depends: let us always live upon this heavenly manna. Thus said some of the wiser and better part of them, though they did not yet fully understand his meaning. Jesus said unto them Proceeding to give them a clear and full explication of the important truth he spoke of; I am the bread of life Having life in myself, and giving life to all that believe in me: nor is bread so necessary to the support of your bodies, as a believing regard to me is to the life of your souls. He that cometh unto me shall never hunger Shall not be destitute of spiritual nourishment; and he that believeth on me shall never thirst Shall find the most restless desires of his soul satisfied, and being conscious of having already received the noblest refreshment and nourishment, shall grow up to a state of complete and everlasting satisfaction and enjoyment. To come to him, and believe on him, are equivalent expressions; or are corresponding terms, explaining each other. Thus our Lord assigned one of the many reasons why he called himself the bread of life. See John 6:47-51. The conclusion from this part of his discourse was so evident, that he left his hearers to draw it for themselves. It was this, “Since matters are so, I am evidently greater than Moses, even in respect of that for which you extol him most. He gave your fathers manna, which was bodily food only, and nourished nothing but the natural life. But I am myself the bread of life and food of the soul, making men both immortal and happy.”
