When a nation turns away from faith, its social fabric quickly unravels. After rebuking the people for their lack of belief and their denial of divine providence, the prophetic focus shifts toward moral corruption and the everyday sins committed between people [מלבי״ם]. Rather than embracing the expected paths of kindness and justice, the nation chose a completely opposite direction [רד״ק, מצודת דוד].
A general consensus among commentators views the nation as a deceitful merchant [מצודת ציון, מלבי״ם, ביאור שטיינזלץ]. Relying heavily on financial profits, this merchant develops a false sense of security through wealth and ultimately abandons the worship of God [רש״י]. In his hands, he holds rigged scales specifically designed to cheat and defraud unsuspecting buyers [מצודת ציון, מלבי״ם]. Alongside this professional comparison, another perspective suggests the imagery connects to the biblical figure of Canaan, the son of Ham, serving as a timeless symbol of a rebellious and criminal nature [אברבנאל].
This deep-seated corruption is further defined by a love for exploitation. The primary approach among commentators is that this applies directly to the merchant, who constantly desires to oppress others, takes pleasure in taking advantage of people, and actively distances himself from kindness and justice [מצודת דוד, מלבי״ם, רד״ק]. However, a contrasting viewpoint suggests that this love of oppression describes the people themselves. According to this perspective, the people of Ephraim do not merely act as deceitful merchants, but they actively admire and love the corrupt merchant specifically because he robs and exploits. This admiration for a cheat reveals the absolute depth of their moral decay [אברבנאל].
