Till she brought forth her firstborn son… From these words Helvidius and other heretics most impiously inferred that the blessed Virgin Mary had other children besides Christ; but St. Jerome shews, by divers examples, that this expression of the Evangelist was a manner of speaking usual among the Hebrews, to denote by the word until, only what is done, without any regard to the future. Thus it is said, Genesis 8. 6 and 7, that Noe sent forth a raven, which went forth, and did not return till the waters were dried up on the earth. That is, did not return any more. Also Isaias 46. 4, God says: I am till you grow old. Who dare infer that God should then cease to be: Also in the first book of Machabees 5. 54, And they went up to mount Sion with joy and gladness, and offered holocausts, because not one of them was slain till they had returned in peace. That is, not one was slain before or after they had returned. God saith to his divine Son: Sit on my right hand till I make thy enemies thy footstool. Shall he sit no longer after his enemies are subdued? Yea and for all eternity. St. Jerome also proves by Scripture examples, that an only begotten son, was also called firstborn, or first begotten: because according to the law, the firstborn males were to be consecrated to God; Sanctify unto me, saith the Lord, every firstborn that openeth the womb among the children of Israel, etc. Ex. 13. 2.

2:3. And king Herod hearing this, was troubled, and all Jerusalem with him.
2:4. And assembling together all the chief priests and the scribes of the people, he inquired of them where Christ should be born.
2:5. But they said to him: In Bethlehem of Juda. For so it is written by the prophet:
2:6. And thou Bethlehem the land of Juda art not the least among the princes of Juda: for out of thee shall come forth the captain that shall rule my people Israel.
2:7. Then Herod, privately calling the wise men learned diligently of them the time of the star which appeared to them;
