--Associated With Sin--
"Ever since Satan spoke his lies through the serpent to Eve, the snake has been associated with sin. The prophets liken the wicked
--to those who “hatch viper’s eggs” (Isaiah 59:5),
--to “a serpent [who] has swallowed us . . . and then has spewed us out” (Jeremiah 51:34),
--and to those who “will lick dust like a snake” (Micah 7:17).
The poetic books speak of
--evil men making “their tongues as sharp as a serpent’s; the poison of vipers is on their lips” (Psalm 140:3),
--of liars having “venom . . . like the venom of a snake, like that of a cobra that has stopped its ears, that will not heed the tune of the charmer, however skillful the enchanter may be” (Psalm 58:4–5),
--and of alcohol eventually biting “like a snake and poison[ing] like a viper” (Proverbs 23:32).
*Jesus and John the Baptist both condemned the hypocrisy of the Pharisees by calling them a “brood of vipers” and “snakes” (Matthew 3:7; 12:34: 23:33)."
