yacca tadvacanaṃ tasya tvayā yacceha bhāṣitam |
ubhayaṃ me garīyastadbrūhi kiṃ karavāṇi te |
bhṛśaṃ prīto'smi bhadraṃ te brahmanstotreṇa te vibho || 23 ||

"Vaisampayana continued, 'Thus addressed by Drona--that utterer of Brahma--Agni, well-pleased at what he heard, and remembering also the promise he had made to Mandapala, replied unto him, saying, 'Thou art a Rishi, O Drona! For what thou hast said is Brahma (Vedic truth). I shall do your pleasure. Fear not! Indeed, Mandapala had spoken to me of you to the effect that I should spare his sons, while consuming the forest. The words he spoke and thy speech also are entitled to great weight to me. Say what I am to do. O best of Brahmanas, I have been greatly pleased with thy hymn. Blest be thou, O Brahmana!'
