pendragon,
Well I hope you are feeling better now …..glad to hear an answer!;)
As to the matter in hand ,Allow me to quote:
“Verse 25: Some modern commentators on Scripture state "the word till does not direct our attention to what happened afterwards; it simply points out what has happened up to that moment." (Navarre Bible Commentary). Examples of this are seen in Matt. 10:11, 12:20, 14:22, 17:9 - "And as they came down the mountain, Jesus charged them, saying: Tell the vision to no man, till the Son of man be risen from the dead."
St. Jerome answers simply that the word 'until' is to be understood in two senses in Scripture. Until often denotes a fixed period, but often also an infinite time, as in the examples below. "Understand then, those things which, if they had not been written might have been doubted, are expressly declared to us; other things are left to our own understanding. So here the evangelist informs us in this area where there might have been room for error, that she was not known by her husband until the birth, that we might infer that much less was she known afterwards."
Gen. 28:15, "And I will be thy keeper where ever you go, and will bring you back into this land: neither will I leave thee, till I shall have accomplished all that I have said."
Isaiah 46:4, God says, "I am till you grow old."
Matthew 22:44, "God said to his divine Son: Sit on my right hand till I make your enemies your footstool."
Verse 25, cont. - Only begotten son was also called firstborn, because, according to the law, Exodus 13:2, "Sanctify unto me, saith the Lord, every firstborn that opens the womb among the children of Israel." The firstborn had other privileges as well: At a certain age his brethren were to honor him by bowing down (Gen. 27:29), he received a "double portion" for an inheritance (Deut. 21:17), he was to take the role as priest in the family, and he was promised special spiritual blessings and privileges (those who blessed him were blessed, those who cursed him were cursed (Gen. 12:1, & 27:29). “
