SB 9.16.36
esa vah kusika viro
devaratas tam anvita
anye castaka-harita-
jaya-kratumad-adayah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Visvamitra said, “O Kusikas [descendants of Kausika], this Devarata is my son and is one of you. Please obey his orders.” O King Pariksit, Visvamitra had many other sons, such as Astaka, Harita, Jaya and Kratuman.
