AVŚ 5.6.4
पर्य् ऊ षु प्र धन्वा वाजसातये परि वृत्राणि सक्षणिः । द्विषस् तद् अध्य् अर्णवेनेयसे सनिस्रसो नामासि त्रयोदशो मास इन्द्रस्य गृहः ॥४॥
pary ū ṣu pra dhanvā vājasātaye pari vṛtrāṇi sakṣaṇiḥ | dviṣas tad adhy arṇaveneyase sanisraso nāmāsi trayodaśo māsa indrasya gṛhaḥ ||4||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Round about do thou run forward in order to the winning of booty, round about overpowering adversaries (vṛtrá, n.); then thou goest over haters by the sea (arṇavá). Weakling (sanisrasá) by name art thou, the thirteenth month, Indra's house.
Translated by William Dwight Whitney (1905)
