Matthew 23:7-9

Amplified Bible

⁷ and to be greeted [with respect] in the market places and public forums, and to have people call them Rabbi. ⁸ But do not be called Rabbi (Teacher); for One is your Teacher, and you are all [equally] brothers. ⁹ Do not call anyone on earth [who guides you spiritually] your father; for One is your Father, He who is in heaven.
