שמות, פרק י״ג, פסוק י״ד

Passing down the historical memory and the reasoning behind the commandments is a foundational educational duty, one that requires tailoring the message to the individual character and capacity of each child [חומש קה״ת]. Unlike the Passover Seder, where the story of the Exodus must be told proactively even without a prompt, this specific educational dialogue is triggered only when the child initiates it [אור החיים, תורה תמימה]. Furthermore, the child’s inquiry must be sincere, reflecting a genuine desire to learn; if the question is posed in mockery, it does not warrant this earnest response [אור החיים].

The timing of the child’s question is interpreted in two distinct ways. The primary approach among commentators is that this refers to a distant future, a time when the visceral, direct memory of slavery and redemption has faded from the nation’s collective consciousness [אבן עזרא, רש״י, רש ר הירש, ביאור יש״ר, תורה תמימה]. Alternatively, the timing can be understood quite literally as the very next day. In this view, the child intentionally waits until the day after the redemption of the firstborn is performed, rather than asking while the money is actively being paid. This restraint highlights his innocence and honesty, ensuring his question is not mistaken for a complaint or a mockery of the financial cost, but is recognized as a pure desire to understand [כלי יקר, פרדס יוסף].

The brevity and general nature of the child's question reveal him to be the "simple son." Unlike a wise child who probes the intricate details of the law, he seeks only to grasp the basic meaning of the commandment [רש״י, כלי יקר, מלבי״ם]. His curiosity centers specifically on the redemption of the firstborn, wondering about the underlying purpose of their unique sanctity [ביאור יש״ר, העמק דבר, שטיינזלץ]. He is especially puzzled as to why this holiness applies to a firstborn donkey—an impure animal—unlike the rest of the livestock [ספורנו].

The father’s answer is carefully calibrated to the child’s straightforward understanding. He explains that God extracted the Israelites from Egypt with overwhelming force, breaking the resistance of their oppressors [ספורנו, רש ר הירש, שטיינזלץ]. This display of power directly references the Plague of the Firstborn, the decisive blow that secured their freedom, making the redemption of Israelite firstborns a lasting memorial to that specific salvation [הטור הארוך]. Furthermore, the reminder that they were brought out of a house of slaves serves as a humbling equalizer: all Israelites were once equal in their bondage, and having been restored to freedom solely by God, they now belong to Him equally [רש ר הירש].

The Exodus serves as the bedrock for all commandments, marking the moment the Israelites accepted God's sovereignty in exchange for His miraculous intervention [ביאור יש״ר]. Because God's leadership transcended the natural order, the Israelites are bound to serve Him through elevated laws that similarly transcend ordinary human logic [הכתב והקבלה]. This divine strength also imparted a greatness of spirit to the firstborns, equipping them to lead a divine regime and inspire the broader nation [העמק דבר].

Regarding the specific inclusion of the donkey, the explanation lies in the haste of the departure. Pressured by the Egyptians to leave immediately, the Israelites could not prepare wagons and had to load their belongings onto donkeys. Because these animals actively participated in the miracle of the redemption, they attained a unique sanctity that requires redemption [ספורנו]. Finally, just as God personally executed the plague against the Egyptian firstborns, the commandment to redeem a firstborn must be performed personally by the individual, rather than being delegated to an agent [פרדס יוסף].
