Wisdom!: Readings from the Fathers of the Church

St John Chrysostom: On the Septuagint

But if, when their mouths are stopped on this point, they should seek another, namely, what is said touching Mary's virginity, and should object to us other translators, saying, that they used not the term "virgin," but "young woman;" in the first place we will say this, that the Seventy were justly entitled to confidence above all the others. For these made their translation after Christ's coming, continuing to be Jews, and may justly be suspected as having spoken rather in enmity, and as darkening the prophecies on purpose; but the Seventy, as having entered upon this work an hundred years or more before the coming of Christ, stand clear from all such suspicion, and on account of the date, and of their number, and of their agreement, would have a better right to be trusted.

--St. John Chrysostom, Homily 5 on Matthew, par. 4
