Srimad Bhagavatam Canto 04, Chapter 17, Text 04

SB 4.17.4

prakrtya visama devi
krta tena sama katham
tasya medhyam hayam devah
kasya hetor apaharat
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The surface of the earth is by nature low in some places and high in others. How did King Prthu level the surface of the earth, and why did the King of heaven, Indra, steal the horse meant for the sacrifice?
