RV 10.12.7
यस्मिन् देवा विदथे मादयन्ते विवस्वतः सदने धारयन्ते । सूर्ये ज्योतिर् अदधुर् मास्य् अक्तून् परि द्योतनिं चरतो अजस्रा ॥
yasmin devā vidathe mādayante vivasvataḥ sadane dhārayante | sūrye jyotir adadhur māsy aktūn pari dyotaniṃ carato ajasrā ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
They in the synod where the Gods rejoice them, where they are seated in Vivasvan's dwelling, Have given the Moon his beams, the Sun his splendour-the Two unweariedly maintain their brightness.
Translated by Ralph T. H. Griffith (1896)
