A.T. Robertson Commentary Matthew 1:23

"Behold, the virgin shall be with child, and shall bring forth a son, And they shall call his name Immanuel; which is, being interpreted, God with us." — Matthew 1:23 (ASV)

They shall call (καλεσουσιν). Men, people, will call his name Immanuel, God with us. "The interest of the evangelist, as of all New Testament writers, in prophecy, was purely religious" (Bruce). But surely the language of Isaiah has had marvellous illustration in the Incarnation of Christ. This is Matthew's explanation of the meaning of Immanuel, a descriptive appellation of Jesus Christ and more than a mere motto designation. God's help, Jesus=the Help of God, is thus seen. One day Jesus will say to Philip: "He that has seen me has seen the Father" (John 14:9).
