Dhammapada · 21.6

Mātaraṃ pitaraṃ hantvā, rājāno dve ca sotthiye;Veyyagghapañcamaṃ hantvā, anīgho yāti brāhmaṇo.

Mataram pitaram hantva, rajano dve ca sotthiye; Veyyagghapancamam hantva, anigho yati brahmano.

Having killed mother and father and two learned kings and a fifth — a tiger — the brahmin goes untroubled.
