Rig Veda
स इत्स्वपा॒ भुव॑नेष्वास॒ य इ॒मे द्यावा॑पृथि॒वी ज॒जान॑ । उ॒र्वी ग॑भी॒रे रज॑सी सु॒मेके॑ अवं॒शे धीर॒: शच्या॒ समै॑रत् ॥ स इत्स्वपा भुवनेष्वास य इमे द्यावापृथिवी जजान । उर्वी गभीरे रजसी सुमेके अवंशे धीरः शच्या समैरत् ॥
Verily he was the doer of a good work in the regions, who genitive rated these two, Heaven and Earth, and firm of purpose, gave an impulse by his deed to the two vast immoveable, beautiful, unsupported worlds.
