7:14-16. Though Ahaz refused to request a sign that would have confirmed the truth of Isaiah’s message, the prophet said God would give him one anyway. The sign was to be a boy named Immanuel. Three elements pertain to the sign: (1) The boy would be born of a virgin (v. 14). (2) He would be raised in a time of national calamity (v. 15; on the curds and honey see comments on v. 22). (3) While he was still a youth, the two-king alliance would be broken (v. 16).
“Virgin” translates ‘almâh, a word used of an unmarried woman of marriageable age. The word refers to one who is sexually mature. It occurs elsewhere in the Old Testament only in Genesis 24:43 (“maiden”); Exodus 2:8 (“girl”); Psalm 68:25 (“maidens”); Proverbs 30:19 (“maiden”); Song of Songs 1:3 (“maidens”); 6:8 (“virgins”). It also occurs in 1 Chronicles 15:20 (alamoth) and in the title of Psalm 46 (alamoth may be a musical term). The child’s name Immanuel means “God (is) with us.”
Most Bible scholars hold one of three views on the virgin in Isaiah 7:14-16: (1) The boy of whom Isaiah wrote was conceived shortly after Isaiah spoke this message. A young woman, a virgin, married and then had a baby. Before he would be old enough to tell the difference between good and evil the northern Aram-Israel alliance would be destroyed. According to this view the woman was a virgin when Isaiah spoke his prophecy but was not when the boy was born because he was conceived by sexual relations with her husband. Some say this child was born to Isaiah (8:3-4). They point out that 8:1-4 corresponds in a number of ways to 7:14-17. But this view must be rejected because (a) Isaiah’s wife already had a child (Shear-Jashub, v. 3) and so was not a virgin, and (b) the second child born to Isaiah’s wife was not named Immanuel (8:3). In this view Ahaz would have known this woman, and hearing of the child’s birth and his name Immanuel he would understand that Isaiah’s prophecies were correct.
(2) A second view sees the predicted birth as exclusively messianic and the virgin as Mary, Jesus’ mother. It is argued that in Isaiah 7:14 the virgin is said to be with child (lit., “the virgin is or will be pregnant”). It is also argued that Matthew, stressing the fact that Joseph and Mary’s marriage was not consummated till after Jesus’ birth (Matt. 1:18, 25), affirmed that Jesus’ birth fulfilled Isaiah’s prophecy (Matt. 1:21-23).
Proponents of this view point out that since Isaiah spoke this prophecy to the house of David (Isa. 7:13) and not just to Ahaz himself, the sign was given not just to the king but to the entire kingly line and the entire nation. However, if the fulfillment did not occur until Joseph and Mary’s day, how does the prophecy relate to Isaiah’s point that the Aram-Israel confederacy would soon be defeated? And how does the birth of the Lord Jesus relate to the eating of curds and honey (v. 15) and to the breaking of the alliance before the boy was old enough to know good and evil? (v. 16) Proponents of this view answer that the time is similar: the two years of Jesus’ babyhood (before He would know between right and wrong) point to the same time segment, two years, within which the Aram-Israel threat would be gone.
(3) A third view, a combination of the first two, sees the prophecy as directed primarily to Ahaz regarding the breaking of the alliance. The ‘almâh was a virgin when Isaiah spoke his message, but then she would marry and have a baby. When the Aram-Israel alliance was broken the boy would still be young. Centuries later the Holy Spirit led Matthew to quote Isaiah 7:14 as a statement that was also true of a virgin birth (i.e., a birth to a woman who was still a virgin). This is the first of many prophecies about the Messiah given by Isaiah. (See the chart “Messianic Prophecies in the Book of Isaiah.”)
The sign must have had some significance for the historical situation in which it was given. The sign involved not only the birth and the boy’s name (Immanuel, “God [is] with us,” would assure the people of God’s presence), but also a designated length of time: before the boy knows enough to reject the wrong and choose the right, the land of the two kings … will be laid waste.
Within about three years (nine months for the pregnancy and two or three years until the boy would know the difference between good and evil) the alliance would be broken. It was broken in 732 B.C. when Tiglath-Pileser III destroyed Damascus. After Tiglath-Pileser had defeated Aram and put Rezin to death Ahaz went to Damascus to meet the Assyrian monarch (2 Kings 16:7-10). Ahaz liked an altar he saw in Damascus, and had a sketch of it drawn so a similar altar could be set up in Jerusalem. No wonder Isaiah and God were angry with Ahaz. Even after the alliance had been broken by Tiglath-Pileser Judah had no peace. Though Assyria did not defeat Judah, she had to pay Assyria a heavy tribute. Isaiah foretold the consequences of Ahaz’s attitude (Isa. 7:17-25).
