AVŚ 8.3.9
तीक्ष्णेनाग्ने चक्षुषा रक्ष यज्ञं प्राञ्चं वसुभ्यः प्र णय प्रचेतः । हिंस्रं रक्षांस्य् अभि शोशुचानं मा त्वा दभन् यातुधाना नृचक्षः ॥९॥
tīkṣṇenāgne cakṣuṣā rakṣa yajñaṃ prāñcaṃ vasubhyaḥ pra ṇaya pracetaḥ | hiṃsraṃ rakṣāṃsy abhi śośucānaṃ mā tvā dabhan yātudhānā nṛcakṣaḥ ||9||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
With sharp eye, O Agni, defend thou the sacrifice; conduct it forward to the Vasus, O forethoughtful one; thee that art harmful, greatly gleaming against the demons, let not the sorcerers injure, O men-watcher.
Translated by William Dwight Whitney (1905)
