The Great Epic of the Bhārata dynasty 1.84.2

1.84.2

ahaṃ hi pūrvo vayasā bhavadbhyastenābhivādaṃ bhavatāṃ na prayuñje |
yo vidyayā tapasā janmanā vā vṛddhaḥ sa pūjyo bhavati dvijānām || 2 ||

"Yayati said, 'I am Yayati, the son of Nahusha and the father of Puru. Cast off from the region of the celestials and of Siddhas and Rishis for having disregarded every creature, I am falling down, my righteousness having sustained diminution. In years I am older than you; therefore, I have not saluted you first. Indeed, the Brahmanas always reverence him who is older in years or superior in learning or in ascetic merit.'
