RV 10.87.9
तीक्ष्णेनाग्ने चक्षुषा रक्ष यज्ञम् प्राञ्चं वसुभ्यः प्र णय प्रचेतः । हिंस्रं रक्षांस्य् अभि शोशुचानम् मा त्वा दभन् यातुधाना नृचक्षः ॥
tīkṣṇenāgne cakṣuṣā rakṣa yajñam prāñcaṃ vasubhyaḥ pra ṇaya pracetaḥ | hiṃsraṃ rakṣāṃsy abhi śośucānam mā tvā dabhan yātudhānā nṛcakṣaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
With keen glance guard the sacrifice, O Agni: thou Sage, conduct it onward to the Vasus. Let not the fiends, O Man-beholder, harm thee burning against the Raksasas to slay them.
Translated by Ralph T. H. Griffith (1896)
