Poison
Poison is a harmful substance that can injure or kill. In Scripture it appears mainly as an image for deadly speech, moral corruption, deceit, or treachery, though it can also refer to literal danger.

A biblical image of something deadly, corrupting, or harmful, often applied to speech, deceit, and sin.
Poison is not a central doctrinal term in Scripture, but it appears as both a literal danger and a vivid metaphor for sin’s destructive effects. Biblical passages speak of venom or poisonous substances in connection with serpents and mortal threat, and they also use poison imagery to describe corrupt speech, deceit, injustice, and the deadly influence of evil. In this figurative sense, poison highlights how words and wickedness can spread harm beyond what is immediately seen. Because the Bible does not develop "poison" as a formal theological concept, the safest treatment is to present it as a biblical image and occasional physical reality rather than as a standalone doctrine.
The Bible most often uses poison language in poetic and wisdom settings to portray the danger of the wicked and the harm of sinful speech. The image emphasizes hidden, spreading, and deadly effects rather than simply physical toxicity.
In the ancient world, poison was known as a real threat in warfare, assassination, and animal venom. That background helps explain why biblical writers could use poison language so powerfully to describe lethal harm and treachery.
Ancient Jewish readers would naturally connect poison imagery with venom, bitterness, and lethal evil. In the Hebrew Scriptures, such language commonly functions as moral and poetic imagery rather than as a technical medical category.
Biblical language for poison often overlaps with words for venom, bitterness, or deadly harm. The emphasis is usually descriptive and figurative rather than technical or pharmacological.
Poison imagery underscores the deadly nature of sin, falsehood, and corrupt speech. It shows that evil is not merely abstract; it injures, defiles, and can spread harm to others.
The term functions as a moral metaphor: just as poison can work invisibly and kill from within, so deceit and sinful speech can corrupt a person and a community before the damage is fully seen.
Do not treat every mention of poison or venom as a doctrine about Christian practice. Avoid building theology from Mark 16:18, since the longer ending of Mark is textually disputed. Keep the entry centered on clear biblical usage rather than speculation.
Most biblical uses are figurative. Literal poison appears only occasionally, while the dominant biblical force of the term is moral and poetic: corrupt speech, deceit, and destructive evil.
This entry does not establish a doctrine of snake-handling, poison immunity, or miracle testing. It should be read as biblical imagery and occasional literal danger, not as a prescribed sign of spirituality.
The image warns believers to guard their speech, reject deceit, and take moral evil seriously. What is poisonous in character or language can spread damage far beyond the immediate moment.
