The first-person pronoun marks the speaker's presence and agency in discourse. In ancient Greek it appears in strengthened forms like ἔγωγε ('I at least', 'for my part') that add emphasis or contrast. The oblique cases derive from a different root, creating the familiar genitive ἐμοῦ and dative ἐμοί. Biblical authors use this pronoun to express personal testimony, divine self-revelation, and emphatic claims about identity and authority.
