John 6:30-32

John 6:30-32. They said therefore unto him, 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. Then Jesus said unto 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.

Jesus did not say to them, "I gave that bread to your fathers in the wilderness," as he might truly have said. It was not Moses who fed their fathers in the wilderness, it was God who had fed them, and if they would but think, they would clearly see that it was so. But the Master took them on to another tack, and led their thoughts to a higher topic.
