SB 10.38.41
papraccha sat-krtam nandah
katham stha niranugrahe
kamse jivati dasarha
sauna-pala ivavayah
Translation:
Nanda Maharaja asked Akrura: O descendant of Dasarha, how are all of you maintaining yourselves while that merciless Kamsa remains alive? You are just like sheep under the care of a butcher.
