Matthew 23:9-12 King James Version (KJV)
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.
