ישעיהו, פרק ז׳, פסוק י״ד

When a person stubbornly refuses to seek divine help or ask for proof, heaven sometimes intervenes by presenting an undeniable reality. Faced with King Ahaz's refusal to request a sign from above, a prophetic promise is delivered directly to him. God grants this sign on His own initiative, placing it before the listeners even though they did not ask for it.

The primary approach among commentators [מלבי״ם, שד״ל, אברבנאל] is that this event is not a supernatural miracle that breaks the laws of nature. Instead, the sign is the very fulfillment of the prophecy. It is a completely natural occurrence set to happen in the near future, serving as a touchstone for the prophet's truth and a guarantee that God will not abandon the people in their time of distress.

The focal point of this event is a specific young woman. There is a general consensus that her description does not necessarily imply she is a virgin. Rather, it refers to a young woman in her prime, possessing a strong and healthy constitution, regardless of whether she is single or married. Her exact identity is a matter of discussion. One approach [רש״י, אבן עזרא, ביאור שטיינזלץ] identifies her as the prophet Isaiah's own wife. Other commentators reject this possibility, noting that the prophet's wife would typically be referred to by a formal title. Consequently, they suggest she is King Ahaz's wife [מצודת דוד, רד״ק], his daughter, or another well-known young woman from the royal court [שד״ל, אברבנאל]. Regardless of her identity, commentators [רש״י, אבן עזרא, אברבנאל] completely reject the idea that the child to be born is King Hezekiah, as chronologically, Hezekiah was born many years before his father Ahaz assumed the throne.

Regarding the pregnancy itself, most commentators explain that the woman was already in the early stages of expecting a child, though her condition was not yet visible or publicly known. A unique perspective [חומת אנך] suggests that the miraculous nature of the sign was that her pregnancy remained entirely unnoticeable until the very moment of birth. Alternatively, another view [רש״י] maintains that the prophecy points to the future, indicating that she will conceive later.

In ancient times, mothers typically chose the names for their sons. Following this custom, the young woman herself will name the child [רד״ק, מצודת דוד, ביאור שטיינזלץ], an act some believe is guided by divine inspiration resting upon her [רש״י]. Another perspective [אברבנאל] suggests that King Ahaz himself will give the child this name, despite his wicked ways. The name given to the child simply means that God is present with the people and actively helping them [מנחת שי]. This naming is not a random detail but the very core of the sign. The child's name stands as a living testimony and an enduring symbol that God will rescue the nation and prevent their enemies from dominating them.
