Matthew 1

22 Now all this happened in order that what was spoken by the Lord through the prophet would be fulfilled, saying,

23 "Behold, the virgin will become pregnant*Literally "will have in the womb" and will give birth to a son,

and they will call his name Emmanuel,"*A quotation from Isa 7:14

which is translated, "God with us."*An allusion to Isa 8:8, 10 in the Greek OT (LXX)
