A sharp confrontation arises against the practice of idolatry, highlighting the absurdity of trading true faith for the worship of inanimate objects and natural forces. Through mockery and rebuke, it becomes clear that the very methods the people use to seek salvation are exactly what will seal their tragic fate.
The primary approach among commentators is that the people selected smooth, beautiful stones from riverbeds to worship as gods [רד״ק, מצודת דוד], or used them to cast lots for ritual purposes [ביאור שטיינזלץ]. By doing so, they tied their fate to these objects [רד״ק, שד״ל]. Instead of embracing God as their rightful portion in life, they chose a worthless lot of stones and sand, a barren environment incapable of growing anything [שד״ל]. What may have begun as simple folk superstitions eventually deteriorated into full-fledged idol worship [ביאור שטיינזלץ]. Another perspective suggests that the devotion was not directed at the stones, but rather at the flowing waters of the streams themselves [שד״ל].
In contrast to the idea that the stones represent the sin, one view suggests they represent the punishment. The smooth river stones are the very rocks that will be used to stone the sinners, bringing them sadness and suffering [רש״י]. However, other commentators reject this interpretation, noting that the surrounding context clearly focuses on the acts of sin rather than the resulting punishment [שד״ל]. A much darker interpretation views the scene not as stone worship, but as a tragic moment of division where the river claims its grim portion: slaughtered children. In their foolishness, the people believed that by murdering their children in the riverbed, the local idols would forge a covenant with them and secure their future [מלבי״ם].
As part of these rituals, the people poured out wine and presented grain offerings [מצודת דוד]. Most commentators explain that these gifts were presented directly to the river stones or the water currents. However, following the perspective of child sacrifice, the offerings were actually poured out for the slaughtered children. The people believed that the sacrificed youths became holy and ascended to the realm of the gods, prompting the living to pour out sacred drinks in their honor [מלבי״ם].
The narrative concludes with a piercing rhetorical question from God. Faced with such severe abominations and evil acts, God asks whether He should reverse His thinking [מצודת ציון], find rest, remain quiet, and act with indifference [שד״ל, ביאור שטיינזלץ]. The commentators agree that this question serves as a firm, absolute declaration: it is completely inappropriate for God to change His mind and hold back the disaster that the people rightfully deserve for their actions [מצודת דוד, רד״ק, אבן עזרא, רש״י].
