Isaiah 7:14

Isaiah 7:14 is a verse of the Book of Isaiah in which the prophet Isaiah, addressing king Ahaz of Judah, promises the king that God will destroy his enemies; as a sign that his oracle is a true one, Isaiah predicts that a young woman will shortly give birth to a child whose name will be Immanuel, "God is with us", and that the threat from the enemy kings will be ended before the child grows up.

The author of the Gospel of Matthew used the Septuagint's translation of the extant Hebrew word almah (a young woman of childbearing age who has not yet had a child) as the Greek parthenos (unequivocally a virgin) in support of his concept of the virgin birth of Jesus. Scholars agree that almah has nothing to do with virginity per se, but many conservative Christians still judge the acceptability of new Bible translations by the way they deal with Isaiah 7:14.
