Dhammapada Verse 100
The Story of Tambadathika
Tambadathika served the king as an executioner of thieves for fifty-five years; he had just retired from that post. One day, after preparing rice gruel at his house, he went to the river for a bath; he had intended to take the specially prepared rice gruel on his return. As he was about to take the rice gruel, Thera Sariputta, who had just arisen from sustained absorption in Concentration (jhana samapatti), stood at his door for alms-food. Seeing the thera, Tambadathika thought to himself, "Throughout my life, I have been executing thieves; now I should offer this food to the thera." So, he invited Thera Sariputta to come in and respectfully offered the rice gruel.
