Dhamma Verses (Dhammapada, KN 2)

9: The Chapter about Wickedness – 119
One should be restrained from what is wrong
Ven. Seyyasaka was unable to maintain his chastity and broke
the same rule again and again; when the Buddha was
informed, he reminded him to keep the precepts and reproved
him with this verse.
117. Pāpañ-ce puriso kay i rā, na taṁ kay i rā punappunaṁ,
na tamhi chandaṁ kay i rātha, dukkho pāpassa uccayo.
Should a person do that which is wicked,
he should not do it again and again,
let him not place his intention in it,
for suffering grows for the wicked one.
