Lukas 20:46-47

Beware of the Sofrim (Rabbonim), the ones wanting to strut around in long kaftans and loving Birkat Shalom greetings in the marketplaces and the rashei hamoshavot (chief seats) in the shuls and the places of kavod at seudos tishen, Which devour the batim (houses) of the almanot (widows) and for the sake of appearance daven lengthy tefillos (prayers): the same shall receive greater damnation.
