King James Version: Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
Simon J. Kistemaker notes that the Greek phrase σαρκὸς ἑτέρας (sarkos heteras, "strange flesh" in the KJV) is often interpreted as the desire on the part of the Sodomites to have sexual relations with angels.
