Matthew 23:10

7 And greetings in the markets, and to be called of men, Rabbi, Rabbi.

8 But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren.

9 And call no man your father upon the earth: for one is your Father, which is in heaven.

10 Neither be ye called masters: for one is your Master, even Christ.

11 But he that is greatest among you shall be your servant.

12 And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.

13 But woe unto you, scribes and Pharisees, hypocrites! for ye shut up the kingdom of heaven against men: for ye neither go in yourselves, neither suffer ye them that are entering to go in.
