With the Brahmin Doṇa 2.4

2.4

Na hi bhavaṃ gotamo brāhmaṇe jiṇṇe vuḍḍhe mahallake addhagate vayoanuppatte abhivādeti vā paccuṭṭheti vā āsanena vā nimanteti.

for the worthy Gotama does not bow to old brahmins, elderly and senior, who are advanced in years and have reached the final stage of life; nor does he rise in their presence or offer them a seat.
