Remigius of Auxerre
Catena Aurea · Matthäusevangelium 1
Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife: And knew her not till she had brought forth her first-born Son: and he called his name JESUS.
Or, Took her so far, as that the nuptial rites being complete, she was called his wife; but not so far as to lie with her, as it follows, And knew her not.
