Dhammapada · 26.10

Yamhā dhammaṃ vijāneyya, sammāsambuddhadesitaṃ;Sakkaccaṃ taṃ namasseyya, aggihuttaṃva brāhmaṇo.

Yamha dhammam vijaneyya, sammasambuddhadesitam; Sakkaccam tam namasseyya, aggihuttamva brahmano.

From whomever one learns the Dhamma taught by the Fully Awakened One — that teacher one should honor reverently, as a brahmin honors the sacrificial fire.
