nava catra gadadayah
vasudevah sutan astav
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
By the semen of Vasudeva in the womb of Devaraksita, nine sons were born, headed by Gada. Vasudeva, who was religion personified, also had a wife named Sahadeva, by whose womb he begot eight sons, headed by Sruta and Pravara.
