RV 5.77.1
प्रातर्यावाणा प्रथमा यजध्वम् पुरा गृध्राद् अररुषः पिबातः । प्रातर् हि यज्ञम् अश्विना दधाते प्र शंसन्ति कवयः पूर्वभाजः ॥
prātaryāvāṇā prathamā yajadhvam purā gṛdhrād araruṣaḥ pibātaḥ | prātar hi yajñam aśvinā dadhāte pra śaṃsanti kavayaḥ pūrvabhājaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
First worship those who come at early morning: let the Twain drink before the giftless niggard. The Asvins claim the sacrifice at daybreak: the sages yielding the first share extol them.
Translated by Ralph T. H. Griffith (1896)
