Watch out. You're eventually going to receive a link with an eleven page essay by Jerome telling you that "until" doesn't really mean "until". :-)
Ask and ye shall receive.
You almost got it right. Actually Jerome responded to Helvidius in an essay defending the The Perpetual Virginity Of Blessed Mary. Yes, the essay is about 11 pages and within these pages he cites several examples of the adverb till used in scripture. For example
Our reply is briefly this -- the words "knew" and "till" in the language of Holy Scripture are capable of a double meaning.
"Now we have to prove that just as in the one case he has followed the usage of Scripture, so with regard to the word "till" he is utterly refuted by the authority of the same Scripture, which often denotes by its ["till"'s] use a fixed time (he himself told us so) [and] frequently time without limitation, as when God by the mouth of the prophet says to certain persons, "Even unto old age I am He" [Is. 46:4]. Will He cease to be God when they have grown old?"
"And the Savior in the Gospel tells the Apostles, "Lo, I am with you always, even unto the end of the world" [Matt. 28:20b]. Will the Lord then after the end of the world has come forsake His disciples, and at the very time when seated on twelve thrones they are to judge the twelve tribes of Israel will they be bereft of the company of their Lord?
There are more but you get the idea.
