RV 10.87.19
सनाद् अग्ने मृणसि यातुधानान् न त्वा रक्षांसि पृतनासु जिग्युः । अनु दह सहमूरान् क्रव्यादो मा ते हेत्या मुक्षत दैव्यायाः ॥
sanād agne mṛṇasi yātudhānān na tvā rakṣāṃsi pṛtanāsu jigyuḥ | anu daha sahamūrān kravyādo mā te hetyā mukṣata daivyāyāḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Agni, from days of old thou slayest demons: never shall Raksasas in fight o'ercome thee. Burn up the foolish ones, the flesh-devourers: let none of them escape thine heavenly arrow.
Translated by Ralph T. H. Griffith (1896)
