John 6:60-63

60So when many of His disciples heard this, they said, “This is a hard teaching. Who can listen to it?”

61But Yeshua knew His disciples were murmuring, so He said to them, “Does this offend you?

62Then what if you see the Son of Man going back up to the place where He was before?

63It is the Spirit who gives life; the flesh is of no benefit. The words I have spoken to you are Spirit and are life!
