RV 4.50.9
अप्रतीतो जयति सं धनानि प्रतिजन्यान्य् उत या सजन्या । अवस्यवे यो वरिवः कृणोति ब्रह्मणे राजा तम् अवन्ति देवाः ॥
apratīto jayati saṃ dhanāni pratijanyāny uta yā sajanyā | avasyave yo varivaḥ kṛṇoti brahmaṇe rājā tam avanti devāḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He, unopposed, is master of the riches of his own subjects and of hostile people. The Gods uphold that King with their protection who helps the Brahman when he seeks his favour.
Translated by Ralph T. H. Griffith (1896)
