Dhamma Verses (Dhammapada, KN 2)

26: The Chapter about Brahmins – 339
The one who is unattached
A brahmin’s wife sought for four brahmins to give a meal to
and was sent the four Arahat novices Saṁkicca, Paṇḍita,
Sopāka and Revata, whom she sat on the floor and would not
serve; being alerted, Sakka came and convinced her to serve
them; the monks could not believe the novices had not got
angry with the woman, but the Buddha confirmed their purity
with this verse.
406. Aviruddhaṁ viruddhesu, attadaṇḍesu nibbutaṁ,
sādānesu anādānaṁ, tam-ahaṁ brūmi brāhmaṇaṁ.
Being friendly with the hostile,
calm amongst those holding a stick,
not attached amongst those attached,
that one I say is a brahmin.
