Repairing the damage caused by theft and false oaths requires a dual process that bridges the social and spiritual worlds. When a person enriches himself at the expense of another, he not only harms his fellow human being but also shows a profound disrespect toward Heaven.
The primary approach among commentators is that bringing an offering to God is only possible after the stolen property has been returned to its rightful owner. The moral wrong on the human level must be fixed first. Returning the stolen goods atones for the sin between people, while the sacrifice repairs the relationship between the individual and God [שד״ל]. This guilt offering, specifically designated for the sin of robbery [ביאור שטיינזלץ], is brought alongside any additional financial penalties the thief might be obligated to pay [אדרת אליהו]. Furthermore, this private obligation remains entirely in effect even if Yom Kippur has already passed, as the holiness of that day does not erase this specific personal debt [מלבי״ם, אדרת אליהו].
The required offering is a mature male ram. This choice is highly symbolic, as the ram represents the power, strength, and material progress of a wealthy individual. The sinner used his power to unlawfully enrich himself while ignoring the boundaries of justice. By bringing a ram, he learns to channel his material ambitions into moral directions, recognizing that true economic success depends on submitting to God's law [רש ר הירש].
To further highlight the economic nature of the offense, this guilt offering requires an animal with a fixed, predetermined monetary value [ביאור שטיינזלץ] of two silver shekels. This minimum price requirement is unique to this specific type of offering [רש ר הירש, אבן עזרא]. Because the crime was intentional, the offender must also add an extra fifth to the principal amount he returns. This extra payment carries a clear educational message. Instead of taking from others to build his own wealth, the offender must learn to give up his own resources for the sake of his fellow man and for holy purposes [רש ר הירש, אבן עזרא].
While the standard understanding is that this entire process applies to a definite, proven act of theft, a rare viewpoint suggests that this offering might actually function as a conditional sacrifice, brought in situations where the sin remains a matter of doubt [אבן עזרא].
