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.
By the false prophets are meant those, who to gain the favour of the multitude attempt to predict future events. The Lord on the mountain pronounces only the blessings of the good, but on the plain he describes also the “woe” of the wicked, because the yet uninstructed hearers must first be brought by terrors to good works, but the perfect need but be invited by rewards.
