מלאכי, פרק ג׳, פסוק ח׳

A piercing rhetorical question challenges the nation: Is it possible for a mere mortal to rob their Creator? Through this bold confrontation, a grim reality is exposed, revealing that the people are failing in their fundamental duties to God. The accusation centers on an act of extortion and taking by force. This specific type of robbery is uniquely associated with the offense of withholding charity and required tithes [מלבי״ם, מצודת ציון, רד״ק]. Such behavior is more than just a financial failure; it is understood as angering the Judge, constituting a direct and personal offense against God [רד״ק].

Confronted with this severe accusation, the people react with feigned innocence, wondering how they could possibly have robbed Him. The clear answer points directly to their withheld tithes and offerings. The primary approach among commentators is that these gifts represent the portion that rightfully belongs to God. Because these contributions are designated to support the priests and Levites who serve as His ministers, anyone who deprives them of this support is considered to be robbing God Himself [רש״י, מצודת דוד, מלבי״ם].

The background to the people's actions stems from deep financial distress. During this period, the nation was suffering from shortages and a severe curse upon their crops. As a result, they justified their stinginess, arguing that they simply could not afford to give generously from the meager yield they had left. However, the prophet corrects this fundamentally flawed mindset. He explains that their logic is entirely backward: it is precisely their act of robbery and their refusal to give the required tithes that is bringing the curse and financial ruin upon them in the first place [אבן עזרא].
