The response of the Egyptian king shifts the confrontation from matters of faith to cold, calculated statecraft, revealing the deep economic, political, and social motives behind the enslavement. Interestingly, the repetitive nature of his speech indicates that these calculations are not spoken aloud to Moses and Aaron. Instead, they represent the king's inner thoughts, carefully concealed to preserve royal dignity [קאסוטו].
The primary approach among commentators is that the king is driven by profound economic anxiety. Managing a massive workforce means that even a brief suspension of labor for a desert festival would result in catastrophic financial losses for the royal treasury [רש״י, רלב״ג, שד״ל, אור החיים, שפתי כהן]. Beyond the immediate financial impact, there is a severe security risk. Granting the slaves free time leads to idleness, which inevitably breeds boredom, rebellious thoughts, and a desire to cast off authority [שד״ל, ביאור יש״ר, שפתי כהן].
The sudden arrival of Moses and Aaron also alters the social dynamics of the kingdom. The simple laborers suddenly feel a sense of prestige, viewing themselves as figures of importance. This newfound self-worth is precisely what causes them to slack off in their duties [הכתב והקבלה]. While most commentators agree that the king's concerns focus on the enslaved Israelites [שטיינזלץ], an alternative viewpoint suggests his anxiety is actually directed toward the Egyptian citizens. The nation relies heavily on the exhausting labor of its own populace. If the slaves are granted a week of vacation, it could spark unrest among the Egyptian working class, who might demand similar rights and ultimately bring about the collapse of the state [רש״ר הירש]. In this light, the attempt to relieve the slaves' burdens is seen as an effort to stop the Egyptians from imposing those burdens, thereby threatening the entire social and governmental order [העמק דבר].
Underlying these practical concerns is a deeper philosophical and legal justification. Confronted with the moral argument that the slaves should be freed due to their suffering, the king reasons that his own royal honor, along with the dignity of the Egyptian masses who benefit from this system, outweighs the pain of the enslaved. Furthermore, he views himself as the absolute legal owner of the laborers and firmly rejects any attempt to strip them from his authority [פני דוד].
Finally, the king cynically dismisses the earlier warning that God might strike the people with disease or war. He calculates that the enslaved population is so vast that the loss of a fraction would be entirely unnoticeable and of no concern to him. In fact, he believes their sheer numbers make them fearless, and allowing them to stop working would only soften their resolve and lead to further complaints [אבן עזרא, אור החיים].
