Translation: 
Śrīla Vyāsadeva taught the first saṁhitā, the Ṛg Veda, to Paila and gave this collection the name Bahvṛca. To the sage Vaiśampāyana he spoke the collection of Yajur mantras named Nigada. He taught the Sāma Veda mantras, designated as the Chandoga-saṁhitā, to Jaimini, and he spoke the Atharva Veda to his dear disciple Sumantu.
