Bede the Venerable
Catena Aurea · Lukasevangelium 6
But woe unto you that are rich! for ye have received your consolation. Woe unto you that are full! for ye shall hunger. Woe unto you that laugh now! for ye shall mourn and weep. Woe unto you, when all men shall speak well of you! for so did their fathers to the false prophets.
But because flattery being the very nurse of sin, like oil to the flames, is wont to minister fuel to those who are on fire with sin, he adds, Woe unto you when all men shall speak well of you.
