SB 9.7.9

yadi viro maharaja
 tenaiva tvam yaje iti
tatheti varunenasya
 putro jatas tu rohitah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O King Pariksit, Hariscandra begged Varuna, “My lord, if a son is born to me, with that son I shall perform a sacrifice for your satisfaction.” When Hariscandra said this, Varuna replied, “Let it be so.” Because of Varuna’s benediction, Hariscandra begot a son named Rohita.
