For he will be great in the sight of the Lord, and he will drink no wine nor strong drink. He will be filled with the Holy Spirit, even from his mother's womb.
      Now the father of John Baptist was a priest, a son of Aaron; his name Zacharias. No families in the world were ever so honoured of God as those of Aaron and David; with one was made the covenant of priesthood, with the other that of royalty; they had both forfeited their honour, yet the gospel again puts honour upon both in their latter days, on that of Aaron in John Baptist, on that of David in Christ, and then they were both extinguished and lost. Christ was of David's house, his forerunner of Aaron's; for his priestly agency and influence opened the way to his kingly authority and dignity. This Zacharias was of the course of Abia. When in David's time the family of Aaron was multiplied, he divided them into twenty-four courses, for the more regular performances of their office, that it might never be either neglected for want of hands or engrossed by a few. The eighth of those was that of Abia (1 Chronicles 24:10), who was descended from Eleazar, Aaron's eldest son; but Dr. Lightfoot suggests that many of the families of the priests were lost in the captivity, so that after their return they took in those of other families, retaining the names of the heads of the respective courses. The wife of this Zacharias was of the daughters of Aaron too, and her name was Elisabeth, the very same name with Elisheba the wife of Aaron, Exodus 6:23. The priests (Josephus saith) was very careful to marry within their own family, that they might maintain the dignity of the priesthood and keep it without mixture.
