The swallow did not leave the prince and go to Egypt because he was deeply moved by the Prince's kindness and compassion for the poor people in the city. The Prince, a statue covered in gold, asked the swallow to help give away his precious gems and gold leaves to the needy. The swallow felt empathy and a sense of duty towards the Prince and the suffering people, choosing to stay and help fulfill the Prince's wishes rather than migrate to Egypt as his flock did. Additionally, the Prince had become blind from giving away his sapphire eyes, and the swallow decided to stay with him for support and friendship. Ultimately, the swallow sacrificed his instinct to migrate out of love, friendship, and selflessness.
