John 2:25

καὶ ὅτι οὐ χρείαν εἶχεν ἵνα τις μαρτυρήσῃ περὶ τοῦ ἀνθρώπου· αὐτὸς γὰρ ἐγίνωσκεν τί ἦν ἐν τῷ ἀνθρώπῳ.

Rough Word-by-word:
and because not need he was having that one he/she might testify concerning the man; he for he was knowing what was in the man.

Smooth Translation:
and because he was not needing that one might testify concerning man, for he himself was knowing what was in man.

Notes:
The imperfects stand out to me in this verse showing Jesus' continual sufficiency (lack of need) and his continual awareness of that which is continually in us (thus our need).
