RV 3.17.3
त्रीण्य् आयूंषि तव जातवेदस् तिस्र आजानीर् उषसस् ते अग्ने । ताभिर् देवानाम् अवो यक्षि विद्वान् अथा भव यजमानाय शं योः ॥
trīṇy āyūṃṣi tava jātavedas tisra ājānīr uṣasas te agne | tābhir devānām avo yakṣi vidvān athā bhava yajamānāya śaṃ yoḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Three are thy times of life, O Jatavedas, and the three mornings are thy births, O Agni. With these, well-knowing, grant the Gods' kind favour, and help in stir aid stress the man who worships.
Translated by Ralph T. H. Griffith (1896)
