Isaiah 7:10-17 records wonderful prophecy of The Virgin who would conceive a child who would bear a significant name with meaning of "God with us!" Thus world's Deliverer was hailed as a child, a Son, given by God Himself & destined to achieve eternal redemption for all sons of Adam that are willing to come to God in appointed way taught in New Testament. Note in the Hebrew that prophecy does not say "a virgin," but "The Virgin", a title that could hardly belong to anyone ever born except Virgin Mary, mother of Jesus. Hebrew word al-mah, is correct word vs: beth-u-lah used to describe Isaac's wife Rebecca, Genesis 24:16 & 43 "neither had she known any man". Isaiah 9:1-5 Is not a prophecy of immediate future when Isaiah delivered it; but predictive prophecy of "last Days" Old Testament related to times of Messiah. Anguish came upon Zeb'-u-lun & Naph'-ta-li in pre-Christian era due partially to their location on northern border of Promised land. They were first to reap bitter fruit of repeated invasions; & Isaiah's prophecy here shows that treatment of lands of these tribes was worse than that of some others, & they would also be first to enjoy benefits of Christ's Preaching coming kingdom. Look at fulfillment passage from Matthew 4:12-16. Isaiah 9:6-7 Five names given the coming Messiah are understood in various ways. Most important is how we understand these five names. It may be these are descriptions of Immanuel's name & not actually names themselves. The Expression-`His name shall be called,' is probably idiomatic for, `This will be His character and nature.'" Notice the Peace and Him ruling on David's Throne.
