[153] When this was said, those young students made an uproar, loud and noisy: "It seems, sirs, the student Ambaṭṭha is ill-born! It seems, sirs, the student Ambaṭṭha is no son of a good family! It seems, sirs, the student Ambaṭṭha is the son of a slavegirl of the Sakyans! It seems, sirs, the Sakyans are the sons of the student Ambaṭṭha's masters! And it seems we presumed that the ascetic Gotama, who speaks only in accordance with the Dhamma, was one who deserved to be rebuked!"
Then it occurred to the Blessed One: "These young students put the student Ambaṭṭha down far too much with the word 'son of a slavegirl.' Why don't I release him from this?"
Then the Blessed One said to those young students: "Young students, do not put the student Ambaṭṭha down too much with the word 'son of a slavegirl.' That Kaṇha was an eminent seer. He went to a southern country, mastered the Brahmā mantras (brahmamantā), approached King Okkāka, and asked for the hand of his daughter Maddarūpī. King Okkāka, thinking, 'Really now! This one, being the son of my own slavegirl, asks for the hand of my daughter Maddarūpī!'—angry and displeased, fitted a razor-tipped arrow (khurappa). But he was able neither to release that arrow nor to withdraw it."
