⁴ sn A quotation from Isa 7:14; 8:8, 10. The Hebrew name Emmanuel literally means “God (is) with us.” This phrase occurs three times in the OT in close proximity, and subsequent uses are likely related to preceding ones. Thus it is very likely the present author had each in mind when he defined the name in v. 23.

² sn I am with you. Matthew’s Gospel begins with the prophecy that the Savior’s name would be “Emmanuel, that is, ‘God with us,’” (1:23, in which the author has linked Isa 7:14 and 8:8, 10 together) and it ends with Jesus’ promise to be with his disciples forever. The Gospel of Matthew thus forms an inclusio about Jesus in his relationship to his people that suggests his deity.

² sn A quotation from Isa 7:14. It is unclear whether the author is citing the MT or the LXX. The use of the word παρθένος (parthenos, “virgin”) may be due to its occurrence in the LXX, but it is also possible that it is the author’s translation of the Hebrew term עַלְמָה (’almah, “young woman”). The second phrase of the quotation is modified slightly from its original context; both the MT and LXX have a second person singular verb, but here the quotation has a third person plural verb form. The spelling of the name here (Emmanuel) differs from the spelling of the name in the OT (Immanuel) because of a different leading vowel in the respective Greek and Hebrew words. In the original context, this passage pointed to a child who would be born during the time of Ahaz as proof that the military alliance of Syria and Israel against Judah would fail. Within Isaiah’s subsequent prophecies this promise was ultimately applied to the future Davidic king who would one day rule over the nation.
