Matthew 9:11; Matthew 9:14; Matthew 13:10; Matthew 15:2-3; Matthew 17:19; Matthew 21:25

11 And when the Pharisees saw it, they said unto his disciples, Why eateth your Master with publicans and sinners?
14 Then came to him the disciples of John, saying , Why do we and the Pharisees fast oft, but thy disciples fast not?
10 And the disciples came , and said unto him, Why speakest thou unto them in parables?
2 Why do thy disciples transgress the tradition of the elders? for they wash not their hands when they eat bread. 3 But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition?
19 Then came the disciples to Jesus apart , and said , Why could not we cast him out ?
25 The baptism of John, whence was it ? from heaven, or of men? And they reasoned with themselves, saying , If we shall say , From heaven; he will say unto us, Why did ye not then believe him?
