### Biblical Occurrences & Contextual Analysis
In the biblical narrative, `{{G5578}}` is used to identify deceptive figures who intentionally mislead. They are described as coming in "sheep's clothing, but inwardly they are ravening wolves" [[Matthew 7:15]]. These false prophets are often associated with performing supernatural acts, as they will "shew great signs and wonders" in order to "deceive the very elect" if possible [[Matthew 24:24]]. A specific individual, Barjesus, is identified as both a "sorcerer" and a "false prophet" [[Acts 13:6]]. In Revelation, the false prophet is a significant figure who works alongside the beast, deceiving people through miracles and ultimately sharing in the beast's judgment in the lake of fire ([[Revelation 19:20]], [[Revelation 20:10]]).
### Related Words & Concepts
Several related words clarify the nature and activity of a false prophet:
* `{{G5572}}` **pseudodidáskalos** (a spurious teacher): This term is used in direct parallel to false prophets, indicating that these figures will introduce "damnable heresies" and even deny the Lord [[2 Peter 2:1]].
* `{{G5580}}` **pseudóchristos** (a spurious Messiah): False prophets are described as rising alongside false Christs, suggesting a shared mission of deception ([[Matthew 24:24]], [[Mark 13:22]]).
* `{{G4105}}` **planáō** (to deceive, go astray, seduce): This verb describes the primary action of a `{{G5578}}`. They will rise and "shall deceive many" [[Matthew 24:11]], using miracles as a tool for their deception [[Revelation 19:20]].

### Theological Significance
The theological weight of `{{G5578}}` is centered on the imperative for spiritual discernment.
* **Deceptive by Nature:** The primary characteristic of a false prophet is intentional deceit. The Bible warns believers to "try the spirits whether they are of God: because many false prophets are gone out into the world" [[1 John 4:1]].
* **Apostasy and Denial:** False prophets are linked to a deeper rebellion against God. They are associated with false teachers who bring in heresies by "denying the Lord that bought them" [[2 Peter 2:1]].
* **Mimicry of Divine Power:** A crucial warning is that false prophets can perform "great signs and wonders" [[Matthew 24:24]]. This indicates that supernatural displays are not, in themselves, proof of a divine source. The false prophet of Revelation deceives through the "miracles which he wrought" [[Revelation 19:20]].
* **Eschatological Judgment:** The role of the false prophet is prominent in end-times prophecy, where this figure is allied with the beast and the dragon [[Revelation 16:13]] and is ultimately defeated and cast into the "lake of fire and brimstone" [[Revelation 20:10]].
