Mbh 7.185.2

“‘Duryodhana said, “No mercy should have been shown to our foes while they were heartless and worn out with toil and taking rest, especially when they are all of sure aim. Desirous of doing what is agreeable to thee, we showed them kindness by then letting them alone. The tired Pandavas, however (having taken rest), have become stronger. As regards ourselves, we are, in every respect, losing in energy and strength. The Pandavas, protected by thee, are constantly gaining prosperity. All weapons that are celestial and all those that appertain to Brahma exist in thee. I tell thee truly, that neither the Pandavas, nor ourselves, nor any other bowmen in the world, can be a match for thee while thou art engaged in battle. O foremost of regenerate ones, thou art acquainted with all weapons. Without doubt, by means of thy celestial weapons thou art capable of destroying the (three) worlds with the gods, the Asuras, and the Gandharvas. The Pandavas are all afraid of thee. Thou, however, forgivest them, remembering that they were thy pupils, or, perhaps, owing to my ill luck.”’
