Matthew 23:10

7 And words of respect in the market-places, and to be named by men, Teacher.

8 But you may not be named Teacher: for one is your teacher, and you are all brothers.

9 And give no man the name of father on earth: because one is your Father, who is in heaven.

10 And you may not be named guides: because one is your Guide, even Christ.

11 But let the greatest among you be your servant.

12 And whoever makes himself high will be made low, and whoever makes himself low will be made high.

13 But a curse is on you, scribes and Pharisees, false ones! because you are shutting the kingdom of heaven against men: for you do not go in yourselves, and those who are going in, you keep back.
