Mbh 6.109.4b

[474] They could not resist that warrior who then resembled the Destroyer himself with wide-open mouth. In that battle on the tenth day, Bhishma, with his sharp shafts, consumed the division of Sikhandin like a conflagration consuming a forest. Him resembling an angry snake of virulent poison, or the Destroyer urged by Death himself, Sikhandin pierced with three shafts in the centre of the chest. Deeply pierced therewith, Bhishma saw that it was Sikhandin (who was piercing him). Excited with wrath, but unwilling (to fight with Sikhandin) Bhishma laughingly said, ‘Whether thou choosest to strike me or not, I will never fight with thee. Thou art that Sikhandin still which the Creator had made thee first’.[475] Hearing these words of his, Sikhandin, deprived of his senses by wrath, and licking the corners of his mouth addressed Bhishma in that battle, saying, ‘I know thee, O mighty-armed one, to be the exterminator of the Kshatriya race. I have heard also of thy battle with Jamadagni’s son. I have also heard much of thy super-human prowess. Knowing thy prowess I will still fight with thee today. For doing what is agreeable to the Pandavas and is agreeable to my own self, O chastiser of foes, I will today fight with thee in battle, O best of men. I will, of a certainty, slay thee. I swear this before thee by my troth! Hearing these words of mine, do that which thou shouldst. Whether thou choosest to strike me or not, thou shall not escape me with life. O thou that art ever victorious, O Bhishma, look thy last on this world.’”
