RV 10.12.3
स्वावृग् देवस्यामृतं यदी गोर् अतो जातासो धारयन्त उर्वी । विश्वे देवा अनु तत् ते यजुर् गुर् दुहे यद् एनी दिव्यं घृतं वाः ॥
svāvṛg devasyāmṛtaṃ yadī gor ato jātāso dhārayanta urvī | viśve devā anu tat te yajur gur duhe yad enī divyaṃ ghṛtaṃ vāḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When the cow's nectar wins the God completely, men here below are heaven's sustainers. All the Gods came to this thy heavenly Yajus which from the motley Pair milked oil and water.
Translated by Ralph T. H. Griffith (1896)
