RV 4.6.8
द्विर् यम् पञ्च जीजनन् संवसानाः स्वसारो अग्निम् मानुषीषु विक्षु । उषर्बुधम् अथर्यो न दन्तं शुक्रं स्वासम् परशुं न तिग्मम् ॥
dvir yam pañca jījanan saṃvasānāḥ svasāro agnim mānuṣīṣu vikṣu | uṣarbudham atharyo na dantaṃ śukraṃ svāsam paraśuṃ na tigmam ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He, Agni, whom the twice-five sisters, dwelling together, in the homes of men engendered, Bright like a spear's tooth, wakened in the morning, with powerful mouth and like an axe well-sharpened.
Translated by Ralph T. H. Griffith (1896)
