Srimad Bhagavatam Canto 08, Chapter 21, Text 23

SB 8.21.23

bhavadbhir nirjita hy ete
 bahuso ’nucara hareh
daivenarddhais ta evadya
 yudhi jitva nadanti nah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Previously, being empowered by providence, you defeated a great number of such followers of Lord Visnu. But today those same followers, having defeated us, are roaring in jubilation like lions.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Bhagavad-gita mentions five causes of defeat or victory. Of these five, daiva (providence) is the most powerful (na ca daivat param balam). Bali Maharaja knew the secret of how he had formerly been victorious because providence was in his favor. Now, since that same providence was not in his favor, there was no possibility of his victory. Thus he very intelligently forbade his associates to fight.
