Mbh 7.102.2

“‘Arjuna said, “I think, O Krishna, that this armour hath been put on Duryodhana’s body by Drona. This armour, tied as it hath been, is impenetrable to my weapons. In this armour, O Krishna, inhereth the might of the three worlds. Only Drona knoweth it, and from that best of men I also have learnt. This armour is not capable of being pierced by my weapons. Maghavat himself, O Govinda, cannot pierce it with his thunder. Knowing it all, O Krishna, why seekest thou to confound me? That which occurred in the three worlds, that which, O Kesava, exists now, and which is in the womb of futurity, are all known to thee. Indeed, O slayer of Madhu, no one else knoweth this better than thou dost. This Duryodhana, O Krishna, cased by Drona in this armours, is staying fearlessly in battle, wearing this coat of mail. That however, which one wearing such armour should do, is not known to him, O Madhava! He weareth it only like a woman. Behold now, O Janardana, the might of my arms and that of my bow too. Though protected by such a coat of mail, I will still vanquish the Kuru prince. The chief of the celestials gave this effulgent armour to Angiras. From the latter it was obtained by Vrihaspati. And from Vrihaspati it was got by Purandara. The Lord of the celestials once more gave it to me with the mantras to be uttered in wearing it. Even if this armour were divine, if it were created by Brahma himself, still the wretch, Duryodhana, struck with my arrows, shall not be protected by it.”’
