G2191 noun

SILEX Entry

Definition

A venomous snake, specifically a viper; used metaphorically for a treacherous or malicious person. In its primary sense, denotes a small but dangerous snake; in extended usage, signifies those seen as deceitful or malicious, especially adversaries or opponents in polemic discourse.

Semantic Range

viper, venomous snake (literal); treacherous or malicious person (metaphorical); source of danger or harm

Root / Etymology

etymology uncertain. The term is attested in classical Greek (e.g., Homer, Hesiod) as ἔχιδνα for 'viper' or 'adder,' but its ultimate origins are not securely established; possibly of pre-Greek or non-Indo-European origin.

Historical & Contextual Notes

In classical and Hellenistic Greek, ἔχιδνα typically refers to a venomous snake, such as a viper, and occurs in literary, medical, and mythological contexts (e.g., Hesiod's Theogony names Echidna as a mythical monster with the characteristics of a serpent). In the LXX and New Testament, the term appears in both literal and metaphorical contexts. In the Gospel traditions, it is famously used by John the Baptist and Jesus in phrases like 'brood of vipers,' which carries the figurative sense of those seen as dangerously crafty or malicious adversaries. English translations often use 'viper,' but this can obscure the strong connotations of harm, danger, and treachery in both literal and figurative uses. Unlike ὄφις (snake, serpent), ἔχιδνα specifically stresses venomous threat. The metaphorical extension in polemical address (e.g., 'offspring of vipers') is present in other Koine sources as a term of sharp invective. In medical writing, it denotes species of venomous snakes known for their potent danger. The figurative sense is not universal in all Greek sources but is frequent in post-classical and biblical contexts and continues in Byzantine usage.
