RV 10.124.8
ता अस्य ज्येष्ठम् इन्द्रियं सचन्ते ता ईम् आ क्षेति स्वधया मदन्तीः । ता ईं विशो न राजानं वृणाना बीभत्सुवो अप वृत्राद् अतिष्ठन् ॥
tā asya jyeṣṭham indriyaṃ sacante tā īm ā kṣeti svadhayā madantīḥ | tā īṃ viśo na rājānaṃ vṛṇānā bībhatsuvo apa vṛtrād atiṣṭhan ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
These wait upon his loftiest power and vigour: he dwells in these who triumph in their Godhead; And they, like people who elect their ruler, have in abhorrence turned away from Vrtra.
Translated by Ralph T. H. Griffith (1896)
