The relationship between God and the people of Israel is often compared to a marriage. When the nation turns to idol worship, their actions are viewed through the painful lens of betrayal, divorce, and prostitution. To confront the people with the depth of their corruption, a well-known Torah law is presented as a logical and legal argument [מלבי״ם, שטיינזלץ].
According to this law, if a husband divorces his wife and sends her away [מצודת ציון], and she then marries another man, the first husband is forbidden from taking her back. Allowing her to return would bring guilt, impurity, and abomination to the land [רד״ק, מצודת ציון, שטיינזלץ]. The commentators agree that this law serves as a sharp metaphor. The nation of Israel is the wife who abandoned her husband, God, to worship idols. The logical conclusion seems clear: if a divorced woman cannot return to her first husband after being with another, surely Israel, having strayed after false gods, cannot return to God [מלבי״ם]. The situation is even more severe because Israel did not merely leave; she acted as a prostitute with many lovers, giving herself over to many different idols [רש״י, מצודת דוד, אברבנאל].
Despite this grim legal reality, the primary approach among commentators is to understand the conclusion of this message as a surprising, grace-filled invitation to return. Even though strict law would naturally prevent such a reunion, God calls Israel back to Him and promises to accept them [רש״י, מצודת דוד, שטיינזלץ]. This extraordinary forgiveness is possible because Israel never truly married the idols. Their connection to false gods was superficial and temporary, driven by a desire to imitate surrounding nations rather than a true, absolute commitment. Because of this, the doors to return remain open [מלבי״ם]. From a legal perspective, another thought is offered: if the separation from God was considered a valid divorce, then acting loosely after the divorce does not legally forbid the woman from returning to her original husband [חומת אנך].
In contrast, a different approach reads the conclusion not as an invitation, but as a sharp rhetorical rebuke. In this view, God asks with astonishment: after chasing after countless idols, do you really think you can simply return to Me? This perspective completely rejects the people's hypocrisy, dismissing the idea that they can hold onto both worlds by worshipping idols while simultaneously trying to serve God [אברבנאל].
