ירמיהו, פרק ה׳, פסוק ח׳

A stark and unsettling picture of moral decay emerges when human behavior descends to the level of unbridled animalistic urges. A direct parallel is drawn between corrupt individuals and horses driven by pure physical appetite.

The primary approach among commentators is that this imagery centers on consumption and satisfaction. Much like horses that are given an abundance of food throughout the night and wake up full of energy, these individuals spend their nights satisfying their deepest lusts and engaging in adultery. By morning, they are completely satiated, proud, and energized by their conquests [מצודת דוד, רד״ק, מצודת ציון]. Other scholars view the animalistic comparison through a more direct lens of sexual desire, likening the people to horses in heat [ביאור שטיינזלץ]. Taking this physical description even further, another perspective suggests they are essentially armed with arousal, equipped with an intense, weapon-like drive that only multiplies their lust [מלבי״ם].

This unyielding drive carries into the start of the new day. Most scholars agree that these individuals are eager, rising at the very first light of dawn to continue pursuing their desires [רש״י, רד״ק, מצודת דוד, מצודת ציון, ביאור שטיינזלץ]. Alternatively, rather than describing the early morning hours, this detail is interpreted anatomically as a reference to the male reproductive organs, serving as a direct continuation of the intense physical lust driving them [מלבי״ם].

The culmination of this behavior is expressed through the loud, distinct neighing sound typical of horses [רש״י, מלבי״ם, מצודת ציון]. In human terms, this neighing represents the sinners loudly rejoicing and boasting about pursuing their neighbors' wives [רד״ק, ביאור שטיינזלץ]. This reveals a profound double layer of moral corruption. The tragedy is not merely that they cross the severe boundary of adultery, but that they actively celebrate their wrongdoing. Instead of feeling a natural sense of shame, they loudly boast about their evil and take pride in their sins [רד״ק, חומת אנך].
