How did Jesus fulfill Isaiah's prophesy?

A:The prophet Isaiah never mentioned Jesus, either by name or in any way by which Jesus could be identified. He did not write any prophecy that Jesus fulfilled or could fulfill. There is a well known passage in most Christian Bibles at Isaiah 7:14 that is a supposed prophecy that Jesus would be born of a virgin, but Isaiah never wrote that passage, at least not as we generally read it.

The passage, used by the author of Matthew, comes from the Septuagint, a flawed early Greek translation of the Hebrew scriptures, which says, "Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel." What the prophet Isaiah wrote was, "Therefore the Lord himself shall give you a sign; Behold, the young woman shall conceive, and bear a son, and shall call his name Immanuel." The young woman in question did have a child just a few verses later in Isaiah's book.
