איוב, פרק ל״ט, פסוק ט׳

The limits of human control over the natural world serve as a powerful rebuke against mankind's pride. This reality is illustrated by the existence of creatures that remain entirely independent of humanity. Unlike certain wild animals that can be tamed or subdued to some degree, there is a specific creature, identified as the Re'em [רש״י, רלב״ג], that absolutely refuses to be subjugated [מלבי״ם, אלשיך, שטיינזלץ]. The primary approach among commentators is that this refers to an exceptionally large and powerful wild beast [מצודת ציון, שטיינזלץ]. Other perspectives suggest it might be a desert goat with tall, strong horns, or perhaps a rare, exotic animal from distant lands, similar to an elephant [תקוות אנוש].

The profound challenge presented to humanity asks whether such a mighty creature would ever agree to serve a human master [רש״י, שטיינזלץ]. Its resistance goes far beyond a mere refusal to perform labor; it extends to a complete rejection of human association, even when presented with material comforts. If a person were to offer this animal a place at a feeding trough—a spot typically used to feed and fatten livestock [מצודת ציון, רלב״ג, מלבי״ם]—it would not stay. It would never establish a permanent presence there [מצודת ציון]. Even if provided with endless food and asked for absolutely no work in return, this creature would never choose to remain by the trough to enjoy the easy meal [מלבי״ם, אלשיך]. By its very nature, it is completely independent, refusing to mix with human society or rely on people for its survival [תקוות אנוש].
