EMMANUEL (EMMANUELE; Hebrew 'Immanā'ēl "God [is] with us", Septuagint 'Εμμανουήλ). - Symbolic name (from a customary expression of good wishes: Ex. 3:12; Josh. 1:5, etc.) of the child foretold by Isaiah (7:14) as the "son of the Virgin", to whom the prophet later (8:8) turns ideally, speaking to him of "his land" (in the context = Palestine). In the Gospel (Mt. 1:23) it is referred, with a quotation of Is. 7:14, to Jesus.
The prophecy belongs to a tragic moment in Eastern history. The kings of Damascus, Samaria and others are at war against Tiglath-Pileser III of Assyria, to whom instead the king of Jerusalem, Ahaz (v.), has made an act of submission; tension between Damascus, Samaria and Ahaz; the latter's preparations for a possible siege. Isaiah turns to Ahaz, to encourage neutrality, suggesting its theocratic religious bases: trust in God, rather than in pagan Assyria; no fear regarding the two "smoldering firebrands" (braggarts). As a guarantee of the promise God is willing to give the king a (miraculous) "sign" of his choosing: let him ask for it (Is. 7:11). The king refuses, evidently concerned about the freedom of his policy. The prophet then, turning to the "house of David", rather than to the king, announces: "The Lord himself will give you a sign: Behold, the Virgin (contextually certain sense: Schula) conceives and bears a Son and gives him the name E.". The figure of the child then appears in various connections with historical events in the following prophecies down to ch. 12 ("Book of E.": Is. 7-12), receiving there among other things messianic and divine appellations (p. 5 agg.; 11:1-16). The prophecy, insofar as it is a "demonstrative sign", is not free from difficulties (Riener-Zerwick): it can be, for example, interpreted as single (Vaccari), or as different in the two moments: a sign offered to the king and refused (v. 11) and a sign given to the house of David (v. 14). It has recently been interpreted as Isaiah's announcement to the reigning house that the concern for the preservation of the theocratic dynasty is so far from being a good excuse for refusing to follow the line of conduct marked out by the prophet, that God has already arranged for the birth of the Messiah for the preservation of the throne of David from a "virgin", in other words without the cooperation of man: God, arbiter of Israel and of the world, wants only trust in him (Garofalo). In any case the prophecy, which exegetical and ecclesiastical authorities (Eschir. Bibl., Rome 1927, n. 59) agree in considering directly messianic, is one of the most beautiful and also fruitful for Christian apologetics and preaching.
