Matthew 23:5-9

But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments,

And love the uppermost rooms at feasts, and the chief seats in the synagogues,

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

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

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