ישעיהו, פרק י״ט, פסוק כ׳

A physical symbol in a foreign land can serve as a profound spiritual anchor. In Egypt, such a marker transforms the relationship between the people and God into a lasting covenant of commitment and salvation. The primary approach among commentators is that an established altar and pillar function together as a clear sign and witness to this new covenant [רש״י, מצודת דוד, מלבי״ם, אבן עזרא]. However, another perspective suggests that the sign refers not to physical objects, but to the unfolding historical events themselves [ביאור שטיינזלץ]. The altar stands as living proof that the Egyptians have committed to worshiping God [מצודת דוד].

There is a fascinating distinction between the roles of these symbols. The sign, represented by the pillar, serves to remind the people of the past and symbolizes that God is their ultimate savior. In contrast, the witness, represented by the altar, looks toward the future, warning and encouraging them to continue their worship [מלבי״ם]. As long as the Egyptians hold fast to their faith, this physical presence acts as a guarantee of God's protection [רד״ק], and anyone experiencing sorrow or distress will naturally come to offer sacrifices there [אבן עזרא].

Because of this established relationship, when oppressors and enemies inevitably rise up to corner and attack them [מצודת ציון, מלבי״ם, ביאור שטיינזלץ], the people will cry out for help. Thanks to the merit of the sign and the pillar, God will remember them and come to their rescue [מלבי״ם].

In response to their cries, God will send a savior. Commentators offer two main views on the nature of this rescuer. The first approach understands the description as a title of greatness and importance, indicating that God will send a distinguished human leader or official to deliver them [רש״י, מצודת דוד, מצודת ציון, אבן עזרא, ביאור שטיינזלץ]. Some even identify this mighty deliverer as an angel of God, sent specifically to strike down their foes [רד״ק]. The second approach interprets the savior's role through the lens of conflict, explaining that this figure will actively fight their battles and champion their cause [מלבי״ם, שד״ל, ביאור שטיינזלץ]. This perspective is supported by the idea that the savior will act as a judge, executing true justice upon the enemies of Egypt [רד״ק, שד״ל].
