12.1.18

śuṅgaṃ hatvā devabhūtiṃ kāṇvo 'mātyas tu kāminam /
svayaṃ kariṣyate rājyaṃ vasudevo mahā-matiḥ //

19. Then this earth will, O king, pass on to the kings of Kanva family of very poor merit; Kanva the minister will assasinate the lewd Devabhuti of Sunga dynasty.

20. (Then) Vasudeva, of great intelligence, will himself rule the kingdom, and his son will be Bhumitra and his son Narayana.
