במדבר, פרק ל״ג, פסוק ל״ט

The record of Aaron's final moments carries deeper meaning beyond a simple historical timeline. His exact age—one hundred and twenty-three years—is deliberately linked to the specific location of his physical passing at Mount Hor. While noting the location might seem unnecessary, it serves a crucial purpose in resolving a contradiction with another biblical account that places his death at a location called Moserah [העמק דבר].

The event at Moserah was not a physical passing. Rather, it represented a profound spiritual loss: the fading of Aaron's unique wisdom and ability to instruct, which departed from the community over a period of several days following his physical death. Because of this distinction between the physical and the spiritual loss, his exact age is tied to Mount Hor. This marks the exact moment his body passed away. Had his age been linked to the later spiritual loss at Moserah, he would have already been considered one hundred and twenty-four years old [העמק דבר].
