RV 10.16.2
शृतं यदा करसि जातवेदो ऽथेम् एनम् परि दत्तात् पितृभ्यः । यदा गच्छात्य् असुनीतिम् एताम् अथा देवानां वशनीर् भवाति ॥
śṛtaṃ yadā karasi jātavedo 'them enam pari dattāt pitṛbhyaḥ | yadā gacchāty asunītim etām athā devānāṃ vaśanīr bhavāti ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When thou hast made him ready, Jatavedas, then do thou give him over to the Fathers. When he attains unto the life that waits him, he shall become the Deities' controller.
Translated by Ralph T. H. Griffith (1896)
