RV 4.33.4
यत् संवत्सम् ऋभवो गाम् अरक्षन् यत् संवत्सम् ऋभवो मा अपिंशन् । यत् संवत्सम् अभरन् भासो अस्यास् ताभिः शमीभिर् अमृतत्वम् आशुः ॥
yat saṃvatsam ṛbhavo gām arakṣan yat saṃvatsam ṛbhavo mā apiṃśan | yat saṃvatsam abharan bhāso asyās tābhiḥ śamībhir amṛtatvam āśuḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
As for a year the Rbhus kept the Milch-cow, throughout a year fashioned and formed her body, And through a year's space still sustained her brightness, through these their labours they were made immortal.
Translated by Ralph T. H. Griffith (1896)
