2 Peter 2:16

ἔλεγξιν δὲ ἔσχεν ἰδίας παρανομίας· ὑποζύγιον ἄφωνον, ἐν ἀνθρώπου φωνῇ φθεγξάμενον, ἐκώλυσεν τὴν τοῦ προφήτου παραφρονίαν.

elegxin de eschen idias paranomias· ypozygion aphōnon, en anthrōpoy phōnē phthegxamenon, ekōlysen tēn toy prophētoy paraphronian.

King James Version (KJV)

But was rebuked for his iniquity: the dumb ass speaking with man's voice forbad the madness of the prophet.

Modern English

But he was rebuked for his wrongdoing by a donkey — an animal without speech — who spoke with a human voice and restrained the prophet's madness.
