in opposition to the rumor that Jesus was born illegitimate, Matthew and his predecessors found vindication for their faith in Jesus in Isaiah 7:14. There the Lord promises to give Israel a “sign” of the coming of God’s salvation. Apparently Matthew knew the Hebrew Bible in its Greek translation, where he would have read the following: “The Lord himself shall give you a sign: Behold, a virgin shall conceive and bear a son; and shall call his name Immanuel—God with us” (Isaiah 7:14).
