שמות, פרק מ׳, פסוק י״ד

Preparing the next generation of priests for their sacred service required a specific, orderly process. The command to initiate Aaron's sons into the priesthood unfolds in two distinct stages.

The initial step involves physically bringing them to the entrance of the Tabernacle, establishing the foundation for their new roles. Following their arrival, the second step focuses on their attire. They are dressed in special tunics, which serve as their official priestly garments, visually and practically marking their formal transition into the priesthood [קאסוטו].
