Immanuel

[3] In Christian theology by contrast, based on its use in Isaiah 7:14, the name has come to be read as a prophecy of the Christ, following Matthew 1:23, where Immanuel (Ἐμμανουὴλ) is translated as μεθ ἡμῶν ὁ Θεός (KJV: "God with us"), and also Luke 7:14–16 after the raising of the dead man in Nain, where it was rumoured throughout all Judaea that "God has visited his people" (KJV).

This is generally translated fully in English Bible versions such as "his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace" (KJV).

The defeat and death of both these kings at the hands of the Assyrians is dated around 732 BCE, placing the birth of the Immanuel child late in the reign of Ahaz.

Isaiah points to the dreadful consequences that followed for Judah's northern neighbours, the kingdom of Israel and Aram-Damascus (Syria) when they rebelled in the days of Ahaz and brought the Assyrians down on themselves.

[6] Isaiah 7–8 mentions three children with symbolic names: Shear-jashub, meaning "a remnant shall return"; Immanuel, "God is with us"; and Maher-shalal-hash-baz, "the spoil speeds, the prey hastens".

As for Immanuel, "God is with us", Isaiah might mean simply that any young pregnant woman in 734 BCE would be able to name her child "God is with us" by the time he is born; but if a specific child is meant, then it might be a son of Ahaz, possibly his successor Hezekiah (which is the traditional Jewish understanding); or, since the other symbolic children are Isaiah's, Immanuel might be the prophet's own son.
