Mark 2:17-18

17 When Jesus heard it, he saith unto them, They that are whole have no need of the physician, but they that are sick: I came not to call the righteous, but sinners to repentance.

18 And the disciples of John and of the Pharisees used to fast: and they come and say unto him, Why do* the disciples of John and of the Pharisees fast, but thy disciples fast not?
