After twenty-two years of separation, a highly charged and dramatic encounter unfolds, highlighting a sharp contrast between a brother's internal awareness and his outward behavior. Upon seeing his brothers, Joseph recognizes them instantly. Some commentators suggest this initial identification was sparked by their Canaanite clothing, which stood out distinctly against the local Egyptian attire [קונטרס חיבה יתירה, העמק דבר]. The primary approach among commentators distinguishes between this initial moment and a later realization. At first, Joseph recognized the group as a whole or identified their general facial features, with the specific recognition of each individual brother crystallizing only afterward [אבן עזרא, הכתב והקבלה, כלי יקר].
In contrast, the brothers had no idea who stood before them. When they had sold him, he was a beardless youth. Now, he was a grown man adorned with a beard and dressed as the viceroy of Egypt. The very thought that this powerful ruler could be their lost brother was entirely beyond their imagination [רד״ק, בכור שור].
Fearing that his brothers might eventually recognize him, Joseph immediately took steps to present himself as a complete stranger. Opinions differ on how he achieved this alienation. One approach suggests he used a physical disguise, pulling a turban down over his forehead to obscure part of his face [רמב״ן, רבנו בחיי]. However, the primary approach among most commentators is that the disguise was behavioral. Joseph deliberately altered his demeanor, suppressing his natural humility to project the persona of a harsh and foreign ruler [רש״י, ספורנו, רשב״ם].
Importantly, Joseph did not act out of a desire for revenge, but rather from profound intentions meant for their ultimate benefit [אדרת אליהו]. By withholding his true identity, he prevented a situation where the brothers might flee in overwhelming shame and fear, or try to force him to swear secrecy so that their father Jacob would never discover the truth [בכור שור, חזקוני]. Furthermore, Joseph wanted to test whether they truly regretted their past actions. He guided them through a process of atonement based on the principle of measure for measure. Just as they had once suspected him of being a spy who brought malicious reports to their father, he now accused them of espionage; and just as they had cast him into a pit, he would soon imprison them [כלי יקר, אברבנאל].
To maintain the charade, Joseph spoke to them with intense anger and firmness. His goal was to terrify them, purposely depriving them of the composure and peace of mind they would need to closely examine his face and voice, which might have given him away [רמב״ן, ביאור יש״ר, אברבנאל].
He began his harsh interrogation by asking from where they had come. Commentators note the unusual phrasing of his question. Typically, one asks strangers where they are from. Asking from where they had come carries an undertone of suspicion, as if addressing nomads without a permanent home. It was as though Joseph was signaling that he already knew they were Canaanites, but was aggressively interrogating them to pinpoint their exact point of origin, exactly as a ruler would interrogate suspected spies [העמק דבר, נחלת יעקב].
Caught off guard, the brothers answered that they had come from the land of Canaan to buy food. Their twofold response was intended to answer what they perceived as two underlying questions from the ruler: their origin and their purpose [ביאור יש״ר]. However, some commentators point out that their unprompted addition about buying food is precisely what handed Joseph the excuse to accuse them of espionage. To a suspicious ruler, their excessive talking and hasty self-justification appeared exactly like the behavior of guilty men desperately trying to cover up their true mission [מלבי״ם].
