ישעיהו, פרק ז׳, פסוק ג׳

In times of military crisis and overwhelming fear, a dramatic encounter unfolds between a prophet and a king. Rather than taking place in the royal palace, this meeting occurs at a strategic water source outside the city. Every element of this event, from the individuals present to the specific location, carries a profound hidden message and a subtle rebuke for both the leadership and the nation.

God commands the prophet to go out and meet King Ahaz. Typically, during times of distress, kings actively seek out the counsel of prophets. However, because Ahaz was a wicked and arrogant ruler, he made no such effort. Therefore, God sends Isaiah to intercept him. Ahaz was either hurrying into Jerusalem to hide from his enemies [אברבנאל], or he had ventured outside the city to block the water supplies, hoping to deprive the approaching armies of drinking water, with the prophet sent to delay him [מלבי״ם]. Another perspective suggests this open area was chosen simply because both the king and the public gathered there, allowing the prophet's message to be heard by all [שד״ל].

The prophet is instructed to bring his son, Shear-Yashuv, along with him. The primary approach among commentators is that this refers to Isaiah's biological son, who was given this name as a living prophetic sign. His presence was intended to remind the people that despite the looming danger, a remnant of Judah would eventually repent and return from exile. Seeing the child during this crisis was meant to awaken the nation to this reality [מצודת דוד, רד״ק, מלבי״ם, שד״ל, אברבנאל]. Conversely, another approach suggests that this does not refer to a biological child at all. Instead, it serves as a title for a small, devoted group of disciples who had repented and were considered the spiritual children of the prophet [רש״י, רד״ק, אברבנאל].

The encounter is set at the edge of a specific trench connected to the upper pool. This pool was a stone structure designed to gather rainwater [רד״ק, מצודת ציון, אבן עזרא], and some note it may have been used to raise fish [רש״י]. The trench was a dug channel or aqueduct used to direct and draw the water when necessary [רד״ק, מצודת ציון, מלבי״ם, אבן עזרא]. It was known as the upper pool because it was situated higher up on the mountain slope, with an additional pool located below it [רש״י, מצודת דוד, שד״ל]. Beyond the physical topography, the setting contained a deep spiritual message for the king. The upper pool symbolized Divine providence, while the trench hinted that the ultimate remedy for the king's troubles could only flow from a higher, heavenly source [אברבנאל]. Furthermore, the concept of a pool shares a linguistic root with the idea of blessing [אבן עזרא].

The precise meeting spot is further identified as an elevated path or highway [מצודת ציון, מלבי״ם] leading to a field where workers would wash clothes and spread them out to dry in the sun [רש״י, מצודת דוד, רד״ק]. This specific location was chosen to subtly hint to Ahaz that he needed to wash away his sins and clear his life's path of evil deeds [אברבנאל]. Midrashic traditions add further layers to what happened in this washer's field. One view describes Ahaz submitting to the prophet, placing a perforated washing vessel on his own head as a symbol of humility [רש״י]. Another tradition suggests that Ahaz ultimately merited salvation because he carefully guarded his eyes, refusing to look at the women who were washing their clothes in the field [צאינה וראינה].
