Sanskrit text [Accents, Plain, Transliterated]:

आ॒क॒रे वसो॑र्जरि॒ता प॑नस्यतेऽने॒हस॒: स्तुभ॒ इन्द्रो॑ दुवस्यति । वि॒वस्व॑त॒: सद॑न॒ आ हि पि॑प्रि॒ये स॑त्रा॒साह॑मभिमाति॒हनं॑ स्तुहि ॥
आकरे वसोर्जरिता पनस्यतेऽनेहसः स्तुभ इन्द्रो दुवस्यति । विवस्वतः सदन आ हि पिप्रिये सत्रासाहमभिमातिहनं स्तुहि ॥
ākare vasor jaritā panasyate 'nehasaḥ stubha indro duvasyati | vivasvataḥ sadana ā hi pipriye satrāsāham abhimātihanaṃ stuhi ||

English translation:

“Indra, the enfeebler (of adversaries), is praised as a mine of wealth; he is propitiated by righteous commendations; he is gratified in the dwelling of the offerer of oblations; glorify Indra, the conqueror, the destroyer of his enemies.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

As a mine of wealth: ākare vasoḥ = he is praised to procure his aid in battle, which when successful, is the source of wealth or booty; ākīryate yuddhārtham dhanam atra ityākaro yuddhak, he is celebrated for the sake of war, for therein is wealth, therefore, ākara is the same as yuddha; or, vasoḥ jarayitā = weakener of the foe, vasu here meaning enemy
