שמות, פרק ל״ג, פסוק י״ט

In response to Moses' profound request to witness Divine glory, God establishes the absolute boundaries of human comprehension. A mortal cannot grasp the true essence of God. Instead, human understanding is limited to perceiving His traits, His actions, and the ways in which He guides the world [רמב״ן, ספורנו, קאסוטו]. This revelation occurs at a critical moment when Moses fears that the protective merit of the forefathers has been entirely exhausted. To reassure him, God imparts an eternal method of prayer rooted in a mercy that never ends [רש״י, מזרחי, שפתי חכמים].

God promises to reveal His absolute goodness. The primary approach among commentators is that this goodness represents God's benevolent traits, His ways of kindness, and the entirety of creation that He brought into existence [אור החיים, מלבי״ם, הירש, ספורנו]. Alternatively, this goodness refers to the hidden treasures of reward reserved specifically for the righteous [רבנו בחיי]. The manner in which this revelation occurs is described as a passing over. This is understood either as a public declaration and proclamation [הרא״ש, חזקוני, הדר זקנים], or as a swift, fleeting exposure, since the human mind cannot endure prolonged contact with the Divine light [קאסוטו, הכתב והקבלה]. This experience is not one of physical sight but of mental and spiritual comprehension, where God illuminates Moses' mind and soul so he can fully understand the Creator's guidance [הכתב והקבלה, ביאור יש״ר]. Another perspective suggests that the Divine light will literally reflect and radiate upon Moses' face [רבנו בחיי].

To teach the exact order of prayer for times of distress, God acts as a prayer leader, demonstrating precisely how the Israelites should appeal for compassion [רש״י, ברטנורא]. By calling out each Divine attribute by name, God teaches Moses how these specific names operate and sustain all the worlds [אור החיים, מלבי״ם]. Raising His voice, God declares His own name, titles, and traits, making His methods of leadership known [שד״ל, אבן עזרא, אם למקרא].

A fundamental discussion arises regarding how this Divine grace and mercy are distributed. The primary approach among commentators maintains that God retains absolute sovereignty over His compassion. Grace and mercy are not automatically guaranteed to every wrongdoer. Rather, God grants them only when He desires and only to those deemed worthy by His infinite wisdom, ensuring that sinners do not exploit Divine forgiveness to continue doing evil [רש״י, אבן עזרא, שד״ל, קאסוטו]. Conversely, another approach views this as a promise of unconditional grace, where God bestows His mercy even upon the unworthy as a free gift from His reserves [תורה תמימה, רבנו בחיי]. The distinct concepts of grace and mercy highlight different aspects of Divine interaction. Grace applies when God chooses to elevate a person and grant them favor and honor even if they never asked for it, whereas mercy applies to a person in distress who actively prays for help and is answered [העמק דבר]. Furthermore, grace can be understood as the initial gift of existence and life itself, while mercy is the constant protection and accompaniment God provides throughout every stage of a person's life [רש״ר הירש].
