Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Then, O Vidura, the Lord caused all the kings, both the enemies and those on the side of your fighting nephews, to be killed in the Battle of Kuruksetra. All those kings were so great and strong that the earth seemed to shake as they traversed the warfield.
