RV 4.33.7
द्वादश द्यून् यद् अगोह्यस्यातिथ्ये रणन्न् ऋभवः ससन्तः । सुक्षेत्राकृण्वन्न् अनयन्त सिन्धून् धन्वातिष्ठन्न् ओषधीर् निम्नम् आपः ॥
dvādaśa dyūn yad agohyasyātithye raṇann ṛbhavaḥ sasantaḥ | sukṣetrākṛṇvann anayanta sindhūn dhanvātiṣṭhann oṣadhīr nimnam āpaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When for twelve days the Rbhus joyed reposing as guests of him who never may be hidden, Valley made fair fertile fields, they brought the rivers. Plants spread o'er deserts, waters filled the hollows.
Translated by Ralph T. H. Griffith (1896)
