RV 1.147.4
यो नो अग्ने अररिवां अघायुर् अरातीवा मर्चयति द्वयेन । मन्त्रो गुरुः पुनर् अस्तु सो अस्मा अनु मृक्षीष्ट तन्वं दुरुक्तैः ॥
yo no agne ararivāṃ aghāyur arātīvā marcayati dvayena | mantro guruḥ punar astu so asmā anu mṛkṣīṣṭa tanvaṃ duruktaiḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The sinful man who worships not, O Agni, who, offering not, harms us with double-dealing,-- Be this in turn to him a heavy sentence may he distress himself by his revilings.
Translated by Ralph T. H. Griffith (1896)
