20.17.9

új jāyatāṃ paraśú jyótiṣā sahá bhūyā́ r̥tásya sudúghā purāṇavát |
ví rocatām aruṣó bhānúnā śúciḥ svàr ná śukráṃ śuśucīta sátpatiḥ ||9||

Let the keen axe come forth together with the light: here be, as erst, the teeming cow of sacrifice. Let the Red God shine pure with his refulgent ray, and let the Lord of heroes glow like heaven's clear sheen.
