Matthew 23:10 YLT

⁸  'And ye -- ye may not be called Rabbi, for one is your director -- the Christ, and all ye are brethren;

⁹  and ye may not call 'any' your father on the earth, for one is your Father, who is in the heavens,

¹⁰  nor may ye be called directors, for one is your director -- the Christ.

¹¹  And the greater of you shall be your ministrant,

¹²  and whoever shall exalt himself shall be humbled, and whoever shall humble himself shall be exalted.
