A sharp confrontation unfolds between God and the priests who serve Him, exposing a deep-seated apathy and disrespect toward their holy duties. The priests are accused of degrading the honor of the Temple, yet they hide behind a mask of innocence, denying their actions and demanding to know how they have caused any offense.
In response to their feigned ignorance, God details exactly how they have failed. The offerings they bring to the altar—referred to conceptually as food, a general term encompassing all animal sacrifices—are impure and abominable. When the priests ask how they have caused defilement, they are effectively denying that they have presented anything tainted. God points directly to their treatment of the altar, which functions as His table where offerings are carefully arranged just like a meal.
The primary approach among commentators is that this disrespect took a very practical form: the priests were offering defective animals, such as those that were blind, lame, or sick [רד״ק, אברבנאל]. However, the physical act was only part of the problem. The mere fact that they viewed the altar in their hearts as something of low value was in itself a severe defilement [אבן עזרא, ביאור שטיינזלץ].
Several underlying reasons explain why the priests developed such a degrading view of the altar. On one level, their attitude stemmed from a lack of spiritual understanding mixed with physical disgust. They looked at the blood and animal fats being offered and found the process repulsive, entirely missing the profound meaning behind God's command to bring these sacrifices [רד״ק, מלבי״ם, אברבנאל].
Compounding this spiritual blindness was a practical, economic frustration. The priests resented the heavy labor required to process and precisely divide the meat. Because the portions were meticulously distributed among many, each priest ultimately received a tiny amount of food, sometimes no larger than an olive or a bean. The intense effort required for such a meager reward led them to treat their sacred work with contempt [רש״י]. Furthermore, they mistakenly compared God's service to the royal courts of human kings. They mocked the Temple procedures, pointing out that the Showbread remained on the table for an entire week instead of being served hot and fresh every day as a human monarch would expect. Through these flawed comparisons and selfish frustrations, they ultimately humiliated the holy table [אהבת יהונתן].
