RV 4.18.7
किम् उ ष्विद् अस्मै निविदो भनन्तेन्द्रस्यावद्यं दिधिषन्त आपः । ममैतान् पुत्रो महता वधेन वृत्रं जघन्वां असृजद् वि सिन्धून् ॥
kim u ṣvid asmai nivido bhanantendrasyāvadyaṃ didhiṣanta āpaḥ | mamaitān putro mahatā vadhena vṛtraṃ jaghanvāṃ asṛjad vi sindhūn ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Are they addressing him with words of welcome? Will the floods take on them the shame of Indra? With his great thunderbolt my Son hath slaughtered Vrtra, and set these rivers free to wander.
Translated by Ralph T. H. Griffith (1896)
