RV 3.19.3
स तेजीयसा मनसा त्वोत उत शिक्ष स्वपत्यस्य शिक्षोः । अग्ने रायो नृतमस्य प्रभूतौ भूयाम ते सुष्टुतयश् च वस्वः ॥
sa tejīyasā manasā tvota uta śikṣa svapatyasya śikṣoḥ | agne rāyo nṛtamasya prabhūtau bhūyāma te suṣṭutayaś ca vasvaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Of keenest spirit is the man thou aidest give us good offspring, thou who givest freely. In power of wealth most rich in men. O Agni, of thee, the Good, may we sing forth fair praises.
Translated by Ralph T. H. Griffith (1896)
