3–6. And Judas begat Phares and Zara of Thamar; and Phares begat Esrom; and Esrom begat Aram; and Aram begat Aminadab; and Aminadab begat Naasson; and Naasson begat Salmon; and Salmon begat Booz of Rachab; and Booz begat Obed of Ruth; and Obed begat Jesse; and Jesse begat David the king.
(in Luc. c. 3.) But Luke has avoided the mention of these, that he might set forth the series of the priestly race immaculate. But the plan of St. Matthew did not exclude the righteousness of natural reason; for when he wrote in his Gospel, that He who should take on Him the sins of all, was born in the flesh, was subject to wrongs and pain, he did not think it any detraction from His holiness that He did not refuse the further humiliation of a sinful parentage. Nor, again, would it shame the Church to be gatheredfrom among sinners, when the Lord Himself was born of sinners; and, lastly, that the benefits of redemption might have their beginning with His own forefathers: and that none might imagine that a stain in their blood was any hindrance to virtue, nor again any pride themselves insolently on nobility of birth.
