Catena Aurea · Matthäusevangelium 23
Fill ye up then the measure of your fathers. Ye serpents, ye generation of vipers, how can ye escape the damnation of hell? Wherefore, behold, I send unto you prophets, and wise men, and Scribes; and some of them ye shall kill and crucify; and some of them shall ye scourge in your synagogues, and persecute them from city to city: That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar. Verily I say unto you, All these things shall come upon this generation.
The rule of the Scriptures is only to know two generations, one of good the other of bad. Of the generation of the good it is said, The generation of the righteous shall be blessed. (Ps. 112:2.) And of thebad it is said in the present passage, Generation of vipers. These then, because they did against the Apostles like things as Cain and Joas, are described as of one generation.
