Pseudo-Chrysostom — as excerpted in the Catena Aurea on Matthew 1:8-11

“What the Holy Spirit testified through the Prophet, saying, that He would cut off every male from the house of Ahab, and Jezebel, that Jehu the son of Nausi fulfilled, and received the promise that his children to the fourth generation should sit on the throne of Israel. As great a blessing then as was given upon the house of Ahab, so great a curse was given on the house of Joram, because of the wicked daughter of Ahab and Jezebel, that his sons to the fourth generation should be cut out of the number of the Kings. Thus his sin descended on his posterity as it had been written, I will visit the sins of the fathers upon the children unto the third and fourth generation. (Exod. 20:5.) Thus see how dangerous it is to marry with the seed of the ungodly.”
