Srimad Bhagavatam Canto 01, Chapter 12, Text 15

SB 1.12.15

tam ucur brahmanas tusta
rajanam prasrayanvitam
esa hy asmin praja-tantau
purunam pauravarsabha
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The learned brahmanas, who were very satisfied with the charities of the King, addressed him as the chief amongst the Purus and informed him that his son was certainly in the line of descent from the Purus.
