Hebrew/Greek Key Terms:
LXX: παρθένος (parthenos) - virgin, rendering the Hebrew almah with the unambiguous Greek term for virgin
Context: Isaiah addresses King Ahaz during the Syro-Ephraimite crisis (735 BC). Ahaz refuses to ask God for a sign, so God gives one anyway: a virgin will conceive and bear a son named Immanuel. Near fulfillment may involve Isaiah's son, but ultimate fulfillment awaits the virgin-born Christ.

Connections:
Connection Method(s): Promise-Fulfillment — Isaiah directly prophesies the virgin birth, specifying how the seed of the woman (Gen 3:15) will come, fulfilled precisely in Jesus' birth from Mary (Matt 1:18-25; Luke 1:26-38), demonstrating His unique identity as "God with us."
Christological Connection: Isaiah 7:14 specifies HOW the seed of the woman (Genesis 3:15) will come — through virginal conception. The protoevangelium spoke of "her seed," an unusual phrase pointing to birth without ordinary male generation. Isaiah 7:14 develops this: the עַלְמָה (almah) — rendered παρθένος (parthenos, "virgin") by the LXX — will conceive and bear a son named Immanuel, "God with us." The sign is extraordinary not merely in the mode of conception but in the identity of the child: a human child bearing a divine name.
Jesus, born of the Virgin Mary, fulfills this precisely (Matthew 1:18-25; Luke 1:26-38). Matthew explicitly quotes Isaiah 7:14 as fulfilled in Christ's birth (Matt 1:22-23). The virgin birth demonstrates that Jesus is uniquely the seed of the woman — not descended from Adam through the male line, breaking the chain of sin transmitted through Adam's federal headship (Romans 5:12). He is the new beginning Eve's naming anticipated: truly "of the woman," yet without the sin-nature inherited through ordinary generation.
The escalation from the original sign to its fulfillment is immense. In Isaiah's immediate context, the sign may have involved a young woman of the royal court bearing a child whose early years would mark the timeline of Assyrian invasion. In its ultimate fulfillment, the virgin conceives by the Holy Spirit (Luke 1:35), and the child is not merely named "God with us" symbolically but is God with us ontologically — "the Word became flesh and tabernacled among us" (John 1:14). The trajectory from Eve's motherhood through Isaiah's virgin to Mary's conception is the narrowing of the seed-promise to its singular fulfillment: one woman, one child, one Savior.
Already: Immanuel has come — God is with His people in the person of Christ and through His Spirit (Matthew 28:20). Not yet: the full realization of "God with us" when "the dwelling place of God is with man" in the new creation (Revelation 21:3).
