John Chrysostom
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.
(ex Hom. in Gen. 49.) Not only Elisabeth, but the wives of the Patriarchs also, Sarah, Rebecca, Rachel, were barren, which was counted a disgrace among the ancients. Not that their barrenness was the effect of sin, since all were just and virtuous, but ordained rather for your benefit, that when you saw a virgin giving birth to the Lord, you might not be faithless, or perplexing your mind with respect to the womb of the barren.
