Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
All Commentaries on Matthew 1:23 Go To Matthew 1
Jerome
AD 420
In Isa 7:14; The LXX and three others translate, ‘Thou shalt call,’ instead of which we have here, “They shall call,” which is not so in the Hebrew; for the word, ‘Charathi,’ which all render “Thou shalt call,” may mean, ‘And she shall call,’ that is, The Virgin that shall conceive and shall bear Christ, shall call His name Emmanuel, which is interpreted, ‘God with us.’.
What is spoken to Ahaz then is to be thus understood. This Child, that shall be born of a Virgin of the house of David, shall now be called Emmanuel, that is, God with us, because the events (perhaps delivery from the two hostile kings)will make it appear that you have God present with you. But after He shall becalled Jesus, that is, Saviour, because He shall save the whole human race. Wonder not, therefore, O house of David, at the newness of this thing, that aVirgin should bring forth a God, seeing He has so great might that though yetto be born after a long while, He delivers you now when you call upon Him.
