Catena Aurea · Lukasevangelium 1
There was in the days of Herod, the king of Judæa, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth. And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless. And they had no child, because that Elisabeth was barren, and they both were now well stricken in years. The office was that of the Priesthood, as it is said, A certain Priest of the name of Zacharias.
There were Princes of the Sanctuary or High Priests, both of the sons of Eleazar and the sons of Thamar, whose courses according to their respective services when they entered into the House of God David divided into twenty-four lots, of which the family of Abia (from which Zacharias was descended) obtained the eighth lot. (1 Chron. 24.) But it was not without meaning that the first preacher of the new covenant was born with the rights of the eighth lot; because as the old Covenant is often expressed by the seventh number on account of the Sabbath, so frequently is the new Covenant by the eighth, because of the sacrament of our Lord’s or our resurrection.
