Pseudo-Jerome — as excerpted in the Catena Aurea on Mark 12:18-27

“But in a mystical sense: what can this woman, leaving no seed of seven brothers, and last of all dying, mean except the Jewish synagogue, deserted by the seven-fold Spirit, which filled those seven patriarchs, who did not leave to her the seed of Abraham, that is, Jesus Christ? For although a Son was born to them, nevertheless He was given to us Gentiles. This woman was dead to Christ, nor shall she be joined in the resurrection to any patriarch of the seven; for by the number seven is meant the whole company of the faithful. Thus it is said contrariwise by Isaiah, Seven women shall take hold of one man; (Is. 4:1) that is, the seven Churches, which the Lord loves, reproves, and chastises, adore Him with one faith. Wherefore it goes on: And Jesus answering, said unto them, Do ye not therefore err, not knowing the Scripture, neither the power of God?”
