RV 3.18.2
तपो ष्व् अग्ने अन्तरां अमित्रान् तपा शंसम् अररुषः परस्य । तपो वसो चिकितानो अचित्तान् वि ते तिष्ठन्ताम् अजरा अयासः ॥
tapo ṣv agne antarāṃ amitrān tapā śaṃsam araruṣaḥ parasya | tapo vaso cikitāno acittān vi te tiṣṭhantām ajarā ayāsaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Agni, burn up the unfriendly who are near us, burn thou the foeman's curse who pays no worship. Burn, Vasu, thou who markest well, the foolish: let thine eternal nimble beams surround thee.
Translated by Ralph T. H. Griffith (1896)
