badhyamānaḿ hatārātiḿ
pāśair vāruṇa-mānuṣaiḥ
vārayām āsa govindas
tena kārya-cikīrṣayā
badhyamanam -- in the process of being tied up; hata -- who had killed; aratim -- his enemies; pasaih -- with ropes; varuna -- those of the demigod Varuna; manushaih -- and those of ordinary humans; varayam asa -- checked Him; govindah -- Lord Krishna; tena -- by him (Jarasandha); karya -- some need; cikirshaya -- desiring to fulfill.
The word hataratim means "who has killed his enemies," or "through whom his enemies would be killed." Srila Visvanatha Cakravarti has provided this thoughtful note.
