Who inquired of Jesus the reason for his disciples not fasting?

Matthew: “Then came to him the disciples of John, saying, Why do we and the Pharisees fast oft, but thy disciples fast not?” (ix, 14.)

Luke: “And they [the scribes and Pharisees] said unto him, why do the disciples of John fast often, ... and likewise the disciples of the Pharisees; but thine eat and drink?” (v, 33.)
