Rig Veda
वै॒श्वा॒न॒राय॑ धि॒षणा॑मृता॒वृधे॑ घृ॒तं न पू॒तम॒ग्नये॑ जनामसि । द्वि॒ता होता॑रं॒ मनु॑षश्च वा॒घतो॑ धि॒या रथं॒ न कुलि॑श॒: समृ॑ण्वति ॥ वैश्वानराय धिषणामृतावृधे घृतं न पूतमग्नये जनामसि । द्विता होतारं मनुषश्च वाघतो धिया रथं न कुलिशः समृण्वति ॥
We offer to Agni, who is Vaiśvānara, the augmenter of water, praise (as bland) as pure clarified butter; and the priests and the worshipper incite by their (pious) rites the invoker of the gods to his two-fold function, as a wheelwright fabricates a car.
