The harsh reality of desert travel hinges entirely on the promise of water. When weary merchants finally reach a familiar stream only to find it completely dry, their desperate thirst is met with crushing disappointment. This powerful image of a dried-up riverbed serves as a profound metaphor for betrayal and shattered expectations.
The primary approach among commentators is that this scene captures merchant caravans traveling across vast distances [רלב״ג, רמב״ן]. These groups make their way toward Tema and Sheba, remote and desolate desert regions completely devoid of human settlement or large water sources [רלב״ג, אבן עזרא]. Tema itself is understood to be a low-lying area in the land of Ishmael or a city deep within Arabia [רש״י, ביאור שטיינזלץ]. As these travelers journey through the harsh landscape, they look toward the riverbeds with deep hope and anticipation, expecting to find water to drink. Instead, they face severe disappointment when they discover the streams have completely dried up [רלב״ג, מלבי״ם, רמב״ן].
While the standard view focuses on the caravans seeking water, another perspective suggests a different kind of desperation. In this reading, the thirsty individuals already standing at the empty riverbeds look out in despair at the passing caravans from Tema and Sheba, hoping the merchants might spare a little water [ביאור שטיינזלץ]. Another interpretation paints a picture of total confusion on the road. The travelers, seeking rest, originally directed their path toward Sheba. However, they suddenly found themselves facing the caravans of Tema because they had lost their way and their route had become completely turned around [אלשיך]. Moving away from the literal struggles of travelers, a more poetic approach suggests that the water itself is the subject of the metaphor. In a creative twist, the vanished waters of the stream are described as having drawn a straight line and traveled far away toward the roads of Tema and Sheba, illustrating their absolute disappearance [מצודת דוד].
On a deeper level, this entire desert scene is a pointed message directed at Job's companions. His friends traveled from a distant land to comfort him, and he placed his full hope in their arrival. Yet, just as the vanishing desert stream betrays the thirsty travelers who depend on it, his friends betrayed him. They initially arrived with the speed and force of a rushing river, but rather than offering help and comfort, they mocked him and caused him further pain. Having failed in their purpose, they now turn away from him, ready to join the passing caravans of Tema and Sheba and return to their own land [רמב״ן].
