Srimad Bhagavatam Canto 10, Chapter 31, Text 03

 SB 10.31.3

visa-jalapyayad vyala-raksasad
 varsa-marutad vaidyutanalat
vrsa-mayatmajad visvato bhayad
 rsabha te vayam raksita muhuh
 
Translation: 
 
O greatest of personalities, You have repeatedly saved us from all kinds of danger — from poisoned water, from the terrible man-eater Agha, from the great rains, from the wind demon, from the fiery thunderbolt of Indra, from the bull demon and from the son of Maya Danava.
 
Purport: 
 
Here the gopis imply, “O Krsna, You saved us from so many terrible dangers, so now that we are dying of separation from You, won’t You save us again?” Srila Visvanatha Cakravarti Thakura explains that the gopis mention Arista and Vyoma because, although Krsna had not yet killed these demons, the fact that He would kill them in the future was well known, having been predicted by the sages Garga and Bhaguri at the time of the Lord’s birth.
