Rig Veda
सु॒प्रा॒व्य॑: प्राशु॒षाळे॒ष वी॒रः सुष्वे॑: प॒क्तिं कृ॑णुते॒ केव॒लेन्द्र॑: । नासु॑ष्वेरा॒पिर्न सखा॒ न जा॒मिर्दु॑ष्प्रा॒व्यो॑ऽवह॒न्तेदवा॑चः ॥ सुप्राव्यः प्राशुषाळेष वीरः सुष्वेः पक्तिं कृणुते केवलेन्द्रः । नासुष्वेरापिर्न सखा न जामिर्दुष्प्राव्योऽवहन्तेदवाचः ॥
This hero, Indra, the prompt discomfiter (of foes), who is to be approached with homage, grants special maturity to the presenter of the libation; he is not the kinsman, nor friend, nor relative, of him who offers no libation (to him); he is difficult of access, and the punisher of him who repeats not (his) praise.
