ויקרא, פרק ג׳, פסוק ט״ו

The sacrificial offerings brought to the altar require specific parts of the animal to be burned, and these requirements are carefully matched to the exact type of animal being offered. When reviewing the detailed list of internal organs and fats set aside for a goat, a deliberate omission stands out when compared to the offering of a sheep.

When a sheep is offered, its entire fat tail is included in the portions to be burned. For a goat, however, this part is entirely left out. Commentators explain that this absence is based on a simple, natural difference between the two animals. A goat's tail is not naturally fatty like the tail of a sheep. Because it lacks this fat content, it is not placed on the altar.
