Mbh 8.73.1a

"Sanjaya said, 'Once more Keshava of immeasurable soul said these words unto Arjuna, who, O Bharata, was advancing (to battle), firmly resolved upon slaying Karna, "Today is the seventeenth day, O Bharata, of this terrible massacre of men and elephants and steeds. At the outset vast was the host that belonged to you. Encountering the foe in battle, that host has been very much reduced in numbers, O king! The Kauravas also, O Partha, were numerous at first, teeming with elephants and steeds. Encountering thee, however, as their foe, they have been nearly exterminated in the van of battle! These lords of Earth and these Srinjayas, united together, and these Pandava troops also, obtaining thy invincible self as their leader, are maintaining their ground on the field. Protected by thee, O slayer of foes, the Pancalas, the Matsyas, the Karushas, and the Cedis, have caused a great destruction of thy foes. Who is there that can vanquish the assembled Kauravas in battle? On the other hand, who is there that can vanquish the mighty car-warriors of the Pandavas protected by thee? Thou, however, art competent to vanquish in battle the three worlds consisting of the gods, the Asuras, and human beings, united together. What need I say then of the Kaurava host? Save thee, O tiger among men, who else is there, even if he resemble Vasava himself in prowess, that could vanquish king Bhagadatta? So also, O sinless one, all the lords of earth, united together, are incapable, O Partha, of even gazing at this vast force that is protected by thee. So also, O Partha, it is owing to their having been always protected by thee that Dhrishtadyumna and Shikhandi succeeded in slaying Drona and Bhishma. Who, indeed, O Partha, could vanquish in battle those two mighty car-warriors of the Bharatas, Bhishma and Drona, both of whom were endued with prowess equal to that of Sakra himself?
