After capturing the Midianite kings Zebah and Zalmunna, Gideon interrogates them about the men they slaughtered in the Tabor region during their earlier raids [ביאור שטיינזלץ]. This interrogation is far more than a simple fact-finding mission; it is a calculated legal maneuver. According to the laws of the time, captive kings were not typically executed unless they were guilty of rebellion or specific crimes. By forcing the kings to confess to murdering his brothers without a trial, Gideon aims to establish their guilt and secure the legal justification needed to put them to death [מלבי״ם].
Gideon presses the kings to describe the victims, asking them to point out anyone in the current crowd who might resemble the fallen men [מצודת ציון, רלב״ג]. The kings recall the victims vividly due to their striking physical beauty [ביאור שטיינזלץ]. They tell Gideon that the men looked exactly like him, sharing his exact form and features [מצודת דוד, רד״ק]. Furthermore, they note that the victims carried themselves with the bearing of princes, a regal appearance often resulting from a life raised in luxury and comfort [רד״ק]. This response may have been a purely factual description, though it is equally possible that the captive kings were using flattery in a desperate attempt to find favor with their captor [ביאור שטיינזלץ].
The exact nature of this resemblance is viewed in a few different ways. The primary approach among commentators is that the description emphasized a shared, uniform appearance among all the victims [רש״י, מצודת דוד]. Alternatively, some suggest that only a single individual among the fallen truly resembled a prince [רש״י, רד״ק]. Another perspective notes that Gideon's own sons were present during the interrogation, leading to the interpretation that one of the victims looked like his sons, while the rest resembled Gideon himself [רלב״ג].
A completely different layer of interpretation views the kings' response not merely as a physical description, but as a staunch legal defense. In this reading, the kings offer no apologies, arguing instead that the victims were rebels who deserved to die, just like Gideon. Because the men carried themselves with royal authority, the kings assumed they were Gideon's sons. Consequently, they sentenced them to death under Midianite law, holding them responsible for their father's rebellion against the ruling power [מלבי״ם].
