When the multitude therefore saw that Jesus wasn't there, nor his disciples, they themselves got into the boats, and came to Capernaum, seeking Jesus.
Now many therefore of his disciples, when they heard this, said, [Man,] These are tough sayings; who can hear it? And when Jesus knew in himself that his disciples murmured at it, he said unto them, Does this offend you? What and if you will see the Son of man ascending up where he was before? ( John 6:60-62 )
