ישעיהו, פרק ז׳, פסוק ט״ו

A prophecy of comfort and abundance is captured through the simple image of a growing child. Eating sweet, nourishing foods serves as a symbol of a coming era of peace, when a ruined land will recover and offer its finest produce to its people. This imagery points to a future moment when a young child will reach an age of mental maturity and discernment. The rich butter consumed refers to the fat skimmed from the top of milk [שד״ל]. The idea of rejecting what is bad and choosing what is good refers on a basic level to a child's developing ability to tell the difference between sweet, wholesome foods and things that taste terrible or are completely unfit to eat, like dirt and stones [רד״ק, אבן עזרא, שטיינזלץ].

Commentators offer different perspectives on exactly how and when the child gains this understanding. One approach views this as a natural part of growing up. While infants initially put everything into their mouths without thinking, they eventually reach the end of their nursing period and learn to select sweet foods while pushing away what is bad [שד״ל, שטיינזלץ]. Alternatively, this development is seen as a miraculous event, where the child will instinctively know to choose good and reject bad immediately from birth, long before the typical age of awareness [מצודת דוד, רד״ק]. Another perspective suggests that this discernment comes through habit and training. A wet nurse will feed the child butter and honey so that his nature becomes accustomed to sweetness, causing him to naturally reject bad-tasting foods simply because they are the opposite of what he knows [אברבנאל].

Beyond the physical development of a single child, a diet of butter and honey represents the future condition of the entire nation. At that time, the land of Judah was devastated and living in fear of the invading armies of Aram and Israel. The prophecy is meant to comfort King Ahaz, assuring him that God will have mercy on His people, preserve a remnant, and restore the land to a state of overflowing plenty [רש״י, מלבי״ם]. The child himself acts as a living sign. By the time he grows old enough to distinguish between good and bad—a span of about two or three years—the enemies threatening Judah will collapse, and the land will be saved [שד״ל]. To ensure this sign was meaningful and immediate for Ahaz during his current crisis, the promised child could not have been Hezekiah, as he was already nine years old when these events took place [רד״ק].
