For this cause then is He Saviour. Now Emmanuel is, being interpreted,
With you God
; or as a yearning cry uttered by the prophet, such as this: With us shall be God; according to which it is the explanation and manifestation of the good tidings proclaimed. For
Behold, He saith, the virgin shall conceive and shall bring forth a son; and He, being God, is to be with us. And, as if altogether astonished at these things, he proclaims in regard to these future events that With us shall be God. And yet again concerning His birth the same. prophet says in another place:
Before she that travailed gave birth, and before the pains of travail came on, she escaped and was delivered of a man-child. Thus he showed that His birth from the virgin was unforeseen and unexpected. And again the same prophet says:
Unto us a son is born, and unto us a child is given: and his name shall be called Wonderful Counselor, Mighty God.
