במדבר, פרק כ׳, פסוק כ״ד

The time arrives for Aaron the High Priest to conclude his earthly mission in the desert. He receives the news of his approaching passing, an event deeply tied to the earlier dispute over water that ultimately prevented him from entering the Promised Land. The message that he will be gathered to his people is not an immediate command to die. Rather, it is an advance warning allowing him to prepare, ascend the mountain, and remove his priestly garments [אבן עזרא, ביאור יש״ר]. This early notice is an act of divine kindness, as God informs the righteous of their final day so they can leave a spiritual will for their children [צאינה וראינה].

Being gathered to his people describes Aaron's soul returning to its source [ביאור שטיינזלץ]. He does not experience a standard death, but rather a gentle passing known as a kiss of death. Having fulfilled his purpose in this world, his soul departs the body willingly, filled with joy and a deep desire to cling to God and join the dwelling place of righteous souls [מלבי״ם]. The location of his passing near the border of Edom carries a deeper symbolic meaning. It serves as a sign that in the future, when the kingdom of Edom rises to power, the institution of the High Priesthood will be abolished from Israel [שפתי כהן].

The reason for his death in the desert is rooted in the failure to follow God's instruction [ביאור שטיינזלץ]. God had commanded both Moses and Aaron to speak to the rock and clearly explain the impending miracle to the Israelites. By doing the exact opposite, they caused the people to doubt and suspect that the water was produced through human trickery [ביאור יש״ר, מלבי״ם]. The memory of the waters of dispute serves either as the physical location marking this event or as the direct underlying cause for Aaron's fate [אבן עזרא, ביאור יש״ר, ברכת אשר על התורה].

Since Moses was the one who actually struck the rock and spoke harshly to the people, Aaron's exact share in the guilt requires explanation. One perspective suggests that Aaron is held responsible for his silence. Even though he did not strike the rock himself, his failure to speak up implied agreement with Moses, and he neglected the joint command to speak to the rock [אור החיים]. Another approach highlights a sharp difference between the two leaders. Moses had the ability to choose between striking and speaking. While his choice to strike the rock failed to publicly sanctify God's name, it still achieved a partial fulfillment of performing the miracle. Aaron, on the other hand, had no role in using the staff. His sole responsibility was to join in speaking to the rock. By remaining silent, he completely abandoned the divine command directed at him, making his rebellion against God's word direct and absolute [העמק דבר, ברכת אשר על התורה].
