Rig Veda
त्वम॑ध्व॒र्युरु॒त होता॑सि पू॒र्व्यः प्र॑शा॒स्ता पोता॑ ज॒नुषा॑ पु॒रोहि॑तः । विश्वा॑ वि॒द्वाँ आर्त्वि॑ज्या धीर पुष्य॒स्यग्ने॑ स॒ख्ये मा रि॑षामा व॒यं तव॑ ॥ त्वमध्वर्युरुत होतासि पूर्व्यः प्रशास्ता पोता जनुषा पुरोहितः । विश्वा विद्वाँ आर्त्विज्या धीर पुष्यस्यग्ने सख्ये मा रिषामा वयं तव ॥
You are the sacrificing or the invoking priest, you are the principal (presenter of the offering), the director (of the ceremonies), their performer, or by birth the family priest; thus conversant with all the priestly functions, you perform perfectly the rite; let us not, Agni, suffer injury through your friendship.
