What does Paul mean? Did Israel eat spiritual food when they ate the manna? When the Jews said to Christ, ‘What sign shewest thou then, that we may see, and believe thee? what dost thou work? Our fathers did eat manna in the desert; as it is written, He gave them bread from heaven to eat’, the Lord answered them, ‘Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. For the bread of God is he which cometh down from heaven, and giveth life unto the world’ (John 6:30-33).
