Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When he saw Indra’s carrier elephant thus fatigued and injured and when he saw Indra morose because his carrier had been harmed in that way, the great soul Vrtrasura, following religious principles, refrained from again striking Indra with the club. Taking this opportunity, Indra touched the elephant with his nectar-producing hand, thus relieving the animal’s pain and curing its injuries. Then the elephant and Indra both stood silently.
