πονηρός

G4190 is an adjective for what is evil, wicked, bad, harmful, malicious, or grievous. In several constructions it can function substantivally for an evil person, evil in a broader sense, or the evil one. Its seventy-eight governed forms describe people, thoughts, deeds, speech, days, an age, spiritual beings, a malignant sore, and other harmful realities. Context, agreement, and syntax decide the referent; etymology does not supply a fixed contrast with every other Greek word translated evil.

The form in Matthew 6:13 can be read as deliverance from evil or from the evil one because the genitive construction is formally compatible with both. Personal readings are supported by clear evil-one uses elsewhere, including Matthew 13, Ephesians 6, and 1 John, but a companion should not hide the translation question. Jesus' prayer still teaches dependence on God's deliverance. Other passages locate evil in human hearts, choices, words, and systems, so spiritual opposition never erases human agency or responsibility.

Evil-language can expose harm, but it can also be abused. It must not label opponents, ethnic or religious groups, disabled or ill people, survivors, or people with mental-health symptoms as demonic. It must not replace evidence, due process, safety planning, qualified care, or lawful reporting. Matthew 5:39 does not require a person to remain accessible to an abuser, and spiritual-warfare texts do not authorize coercive exorcism, conspiracy claims, retaliation, or neglect of medical care. Christians resist evil truthfully while remembering that judgment belongs to God and that accused and harmed people both require just process.

Seventy-eight governed forms in seventy-two verses name evil or harmful people, conduct, thoughts, speech, times, spiritual beings, the evil one, and physical affliction across twenty books.
