Srimad Bhagavatam Canto 10, Chapter 04, Text 36

SB 10.4.36

kim ksema-surair vibudhair
 asamyuga-vikatthanaih
raho-jusa kim harina
 sambhuna va vanaukasa
kim indrenalpa-viryena
 brahmana va tapasyata
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The demigods boast uselessly while away from the battlefield. Only where there is no fighting can they show their prowess. Therefore, from such demigods we have nothing to fear. As for Lord Visnu, He is in seclusion in the core of the hearts of the yogis. As for Lord Siva, he has gone to the forest. And as for Lord Brahma, he is always engaged in austerities and meditation. The other demigods, headed by Indra, are devoid of prowess. Therefore you have nothing to fear.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Kamsa’s ministers told Kamsa that all the exalted demigods had fled in fear of him. One had gone to the forest, one to the core of the heart, and one to engage in tapasya. “Thus you can be free from all fear of the demigods,” they said. “Just prepare to fight.”
