Dhammapada Verse 162
The Story of Devadatta
One day, some bhikkhus were talking amongst themselves when the Buddha came in and asked the subject of their talk. They answered that they were talking about Devadatta and then continued as follows:
"Venerable Sir! Devadatta is, indeed, a man without morality; he is also very avaricious. He has tried to gain fame and fortune by getting the confidence of Ajatasattu by unfair means. He has also tried to convince Ajatasattu that by getting rid of his father, he (Ajatasattu) would immediately become a powerful king. Having been thus misled by Devadatta, Ajatasattu killed his father, the noble king, Bimbisara. Devadatta has even attempted three times to kill you, our most Venerable Teacher. Devadatta is, indeed, very wicked and incorrigible!"
