χαλκηδών

In the Greek New Testament, the word χαλκηδών (chalkēdōn) appears only once. Based on its short definition, χαλκηδών refers to a type of stone called chalcedony. The single occurrence of this word is in the apostle Peter's first epistle (1 Peter 5:8), where he describes false teachers as "like beasts at bay" and likens them to wild animals that are "sharp as knives" (or more accurately, sharp stones such as chalcedony). χαλκηδώn's specific type of meaning likely carries a sense of sharpness and danger, highlighting the threat posed by false leaders.
