Mbh 1.134.11

“Two of Drona’s pupils became very much accomplished in the use of mace. These were Druvodhana and Bhima, who were, however, always jealous of each other. Aswatthaman excelled everyone (in the mysteries of the science of arms). The twins (Nakula and Sahadeva) excelled everybody in handling the sword. Yudhishthira surpassed everybody as a car-warrior; but Arjuna, however, outdistanced everyone in every respect--in intelligence, resourcefulness, strength and perseverance. Accomplished in all weapons, Arjuna became the foremost of even the foremost of car-warriors; and his fame spread all over the earth to the verge of the sea. And although the instruction was the same, the mighty Arjuna excelled all (the princes in lightness of hand). Indeed, in weapons as in devotion to his preceptor, he became the foremost of them all. And amongst all the princes, Arjuna alone became an Atiratha (a car-warrior capable of fighting at one time with sixty thousand foes). And the wicked sons of Dhritarashtra, beholding Bhimasena endued with great strength and Arjuna accomplished in all arms, became very jealous of them.
