Rig Veda
क्व१॒॑ वोऽश्वा॒: क्वा॒३॒॑भीश॑वः क॒थं शे॑क क॒था य॑य । पृ॒ष्ठे सदो॑ न॒सोर्यम॑: ॥ क्व वोऽश्वाः क्वाभीशवः कथं शेक कथा यय । पृष्ठे सदो नसोर्यमः ॥
Where are your horses? where your reins? what is your capability? where are you going? The saddle is on the back (of the steeds), the bridle in their nostrils.
