Immanuel or Emmanuel (Hebrew: עִמָּנוּאֵל, romanized: ʿĪmmānūʾēl, "God [is] with us"; Koine Greek: Ἐμμανουήλ Emmanūēl) is a Hebrew name that appears in the Book of Isaiah (7:14) as a sign that God will protect the House of David. The Gospel of Matthew (Matthew 1:22–23) interprets this as a prophecy of the birth of the Messiah and the fulfillment of Scripture in the person of Jesus. Immanuel "God (El) with us" is one of the "symbolic names" used by Isaiah, alongside Shearjashub, Maher-shalal-hash-baz, or Pele-joez-el-gibbor-abi-ad-sar-shalom.
