Rig Veda
अ॒न्तर्ह्य॑ग्न॒ ईय॑से वि॒द्वाञ्जन्मो॒भया॑ कवे । दू॒तो जन्ये॑व॒ मित्र्य॑: ॥ अन्तर्ह्यग्न ईयसे विद्वाञ्जन्मोभया कवे । दूतो जन्येव मित्र्यः ॥
Sage Agni, you penetrate the innermost (man), knowing the birth of both (the worshipper and the worshipped); like a messenger favourable to men, especially to his friends.
