Isaiah 7:14
Rahlfs Septuagint (1935) · Berean Standard Bible
διὰ τοῦτο δώσει κύριος αὐτὸς ὑμῖν σημεῖον ἰδοὺ ἡ παρθένος ἐν γαστρὶ ἕξει καὶ τέξεται υἱόν καὶ καλέσεις τὸ ὄνομα αὐτοῦ Εμμανουηλ
Therefore the Lord Himself will give you a sign: Behold, the virgin (note: Or young woman) will be with child and give birth to a son, and will call Him Immanuel (note: Immanuel means God with us; literally and she will call His name Immanuel; DSS and His name will be called Immanuel or and He will call His name Immanuel; LXX and you will call His name Immanuel; cited in Matthew 1:23.).
