At Yudhishthira’s Rajasuya sacrifice, the Pandavas offer Krishna the first honor, water to wash his feet. Shishupala, the king of Chedi, mocks Krishna before all the assembled kings: “If this one is the lord of the universe, as this fool representeth him to be, why doth he not regard himself as a Brahmana?”
Krishna replies that he had made a promise to Shishupala’s mother: “a hundred offences (of his) were to be pardoned by me.” Then he says: “That number, ye kings, hath become full.” He cuts off Shishupala’s head with his discus.
