The idea of the Messiah, gradually gathering to itself the attributes of a divine King, reaches one of its clearest expressions in the great Immanuel prophecy, extending from Isaiah 7 to 9:7, and centering in the declaration: “The Lord Himself will give you [the unbelieving Ahaz] a sign; behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel” (Isa. 7:14; Cf. 8:8, 10). This is none other than the child of wonder extolled in chapter 9:6, 7: “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, [Father of Eternity], The Prince of Peace. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom,” etc. This is the prophecy quoted as fulfilled in Christ’s birth in Matt. 1 .23, and it seems also alluded to in the glowing promises to Mary in Luke 1:32, 33. It is pointed out in objection that the term rendered “virgin” in Isaiah does not necessarily bear this meaning; it denotes properly only a young unmarried woman. The context, however, seems clearly to lay an emphasis on the unmarried state, and the translators of the Greek version of the Old Testament (the Septuagint) plainly so understood it when they rendered it by parthenos, a word which does mean “virgin.” The tendency in many quarters now is to admit this (Dr. Cheyne, etc.), and even to seek an explanation of it in alleged Babylonian beliefs in a virgin-birth. This last, however, is quite illusory. It is, on the other hand, singular that the Jews themselves do not seem to have applied this prophecy at any time to the Messiah — a fact which disproves the theory that it was this text which suggested the story of a Virgin birth to the early disciples.
It was, indeed, when one thinks of it, only on the supposition that there was to be something exceptional and extraordinary in the birth of this child called Immanuel that it could have afforded to Ahaz a sign of the perpetuity of the throne of David on the scale of magnitude proposed (“Ask it either in the depth, or in the height above.” Ver. 10). We look, therefore, with interest to see if there are any echoes or suggestions of the idea of this passage in other prophetic scriptures. They are naturally not many, but they do not seem to be altogether wanting. There is, first, the remarkable Bethlehem prophecy in Micah 5:2, 3 — also quoted as fulfilled in the nativity (Matt. 2:5, 6) — connected with the saying: “Therefore will he give them up, until the time that she who travaileth hath brought forth” (“The King from Bethlehem,” says Delitzsch, “who has a nameless one as mother, and of whose father there is no mention”). Micah was Isaiah’s contemporary, and when the close relation between the two is considered (Cf. Isa. 2:2-4, with Micah 4:1-3), it is difficult not to recognize in his oracle an expansion of Isaiah’s. In the same line would seem to lie the enigmatic utterance in Jer. 31:22: “For Jehovah hath created a new thing in the earth: a woman shall encompass a man” (thus Delitzsch, etc.).
