Aviyah
"Therefore the Lord Himself shall give you a sign: Behold, the maiden (almah) conceived and is bringing forth a son, and she will call his name Immanuel" (Yeshaiah 7:14).
Though this verse is also a prophecy of a future mashiach (anointed one), the immediate identity of the maiden and her child is concealed. There are many who have seen King Hizkiyahu (God is my strength) as the likely identity of the one the maiden would call Immanuel (God with us). And Aviyah, which means God is my father, was the maiden who became the mother of Hizkiyahu.
The difficulty of this verse as prophecy about Hizkiyahu and Aviyah has been that the Bible tells us that Hizkiyahu was born several years before Yeshaiah wrote these words, and the prophecy is usually translated entirely in the future tense. However, I have it on good authority that it says "the maiden conceived" – past tense. That is, the one to be called Immanuel had already been conceived at the time of the prophecy of the "sign" to be given to King Ahaz.
Hizkiyahu was a truly messianic figure who turned the southern kingdom of Yehuda back to God shortly before its deportation to Babylon. And God turned back time for Hizkiyahu (2 Kings 20:11) as a sign for him that his death would be delayed, and that the Assyrians would not take his kingdom. This sign seems to be mirrored by Yishaiah's prophetic sign, which also appears to reach into the past – when translated correctly.
Also, alam, a word with the same root as the word translated maiden (almah), means was concealed. Perhaps this hints that the "sign" for the evil king Ahaz was that this maiden (who became his wife) concealed and rescued her son, just as Yocheved had once concealed and rescued her son, Moshe. Yeshaiah's prophecy, then, may have been written to inform the king that his maiden wife, Aviyah, conceived and bore a son, and then escaped with him in order to rescue him from the king's known intent to pass his sons through the fires of Moloch (2 Kings 16:3). It may have been that his magnificent and holy young son would become a sign to Ahaz of his own impotence in the face of God.
Therefore, just as the Queen of Heaven, the subject and speaker of Her Story, has been concealed throughout her existence, the one bearing the name I have chosen for myself as the author, Aviyah, appears to have concealed her son -- and her name conceals me.
