Rig Veda
यथा॑ होत॒र्मनु॑षो दे॒वता॑ता य॒ज्ञेभि॑: सूनो सहसो॒ यजा॑सि । ए॒वा नो॑ अ॒द्य स॑म॒ना स॑मा॒नानु॒शन्न॑ग्न उश॒तो य॑क्षि दे॒वान् ॥ यथा होतर्मनुषो देवताता यज्ञेभिः सूनो सहसो यजासि । एवा नो अद्य समना समानानुशन्नग्न उशतो यक्षि देवान् ॥
Son of strength, invoker (of the gods), in like manner as at the worship of the gods by Manu, you did offer worship with sacrifice; so now, Agni, with willing mind, worship for us the assenting deities, regarding them as your equals.
