Matthew 9:13-15

Young's Literal Translation

¹³ but having gone, learn ye what is, Kindness I will, and not sacrifice, for I did not come to call righteous men, but sinners, to reformation.'

¹⁴ Then come to him do the disciples of John, saying, `Wherefore do we and the Pharisees fast much, and thy disciples fast not?'

¹⁵ And Jesus said to them, `Can the sons of the bride-chamber mourn, so long as the bridegroom is with them? but days shall come when the bridegroom may be taken from them, and then they shall fast.
