Rabbi Eliezer was one of the most formidable scholars in Israel — a man whose rulings could silence an entire academy. So when a slave in his household died and his students came to offer condolences, they were stunned by what happened next.

Rabbi Eliezer turned them away. "I will accept no condolences," he said flatly. His students were confused. A member of his household had died. Surely the laws of mourning applied. Surely some measure of grief was appropriate.

Rabbi Eliezer explained: the formal laws of mourning — sitting shiva, tearing one's garments, receiving condolences — apply only to one's relatives. A slave, under Jewish law, was not a relative. The rituals of mourning did not technically apply.

But his students pressed him. "Even if the law does not require it, does not human decency demand some acknowledgment?" Rabbi Eliezer paused. He was not a cruel man. He was a man of precise legal boundaries. "Say to me what one says upon the loss of an ox or a donkey," he replied. "Say: 'May God replace your loss.' That is the appropriate formula."

The Talmud preserves this story not as a model to follow but as a point of legal debate. Later authorities disagreed sharply with Rabbi Eliezer's coldness. The rabbis ultimately ruled that while formal mourning rites do not apply to slaves, a master who feels genuine grief should express it. A human being is not an ox. The law may draw boundaries, but compassion must sometimes cross them.
