MATTHEW
23:8-12
8 But be not ye called Rabbi; for one is your teacher, and all ye are brethren. 9 And call no man your father on the earth: for one is your Father, even He who is in heaven. 10 Neither be ye called masters: for one is your master, even the Christ. 11 But he that is greatest among you shall be your servant. 12 And whosoever shall exalt himself shall be humbled; and whosoever shall humble himself shall be exalted.
