For Unto Us A Child Is Born

Isaiah 7
14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.

Isaiah 9
6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.

I've been thinking about these two passages, and our savior, Jesus, all day. I could hear Handel's Messiah as I was thinking about them. Good way to work your way through the holiday season.

I was also thinking about the Jews. I have no doubt about God's message, about Jesus, to me, in the above passages from Isaiah. But I wonder what is God's message to the Jews. I assume most Jews think the child that is given is Hezekiah, who is a great Biblical character. And, Isaiah, at the time this passage, must have had Hezekiah, Ahaz's son - and Jesus - in view. This topic appears to be above my pay grade. On the other hand, it pleasant to consider it during the Christmas season.  John Gill references the medieval Hebrew expositor Rashi in Exposition of the Entire Bible.

Rashi Commentary On Isaiah 9:6 (From chabad.org)
For a child has been born to us: Although Ahaz is wicked, his son [Hezekiah] who was born to him many years ago [nine years prior to his assuming the throne] to be our king in his stead, shall be a righteous man, and the authority of the Holy One, blessed be He, and His yoke shall be on his shoulder, for he shall engage in the Torah and observe the commandments, and he shall bend his shoulder to bear the burden of the Holy One, blessed be He.
