What does "dogs" mean in Rev 22:15?
How does Revelation 22:15 define "dogs" in a biblical context?

Scriptural Text

“Outside are the dogs, the sorcerers, the sexually immoral, the murderers, the idolaters, and everyone who loves and practices falsehood.” (Revelation 22:15)


Cultural and Old Testament Background

1. Unclean Status: Dogs were neither domesticated pets nor kosher animals in Israelite culture (cf. Leviticus 11:27).

2. Scavengers and Threats: 1 Kings 14:11; 1 Kings 21:19 depict dogs devouring the wicked, an emblem of divine judgment.

3. Cultic Prostitution: Deuteronomy 23:17-18 forbids Israel to bring “the wages of a dog” (kélèv) into the sanctuary—a euphemism for male cult prostitutes attached to Canaanite fertility rites.

4. Contemptuous Insult: Goliath (“Am I a dog?” 1 Samuel 17:43) and Mephibosheth (“Why should this dead dog curse my lord the king?” 2 Samuel 16:9) illustrate the phrase as a self-humbling or derogatory reproach.


Prophetic and Poetic Usage

Psalm 22:16 portrays encircling enemies as “a pack of dogs.” Isaiah 56:10-11 brands corrupt watchmen “silent dogs” and “greedy dogs.” These texts establish the prophetic pattern of “dog” as a cipher for predatory leaders who fail morally and doctrinally.


New Testament Development

1. Jesus warns against giving “holy things to dogs” (Matthew 7:6), signaling those who despise sacred truth.

2. Paul exhorts, “Beware of the dogs, beware of the evil workers, beware of the mutilators” (Philippians 3:2), targeting Judaizers who distort the gospel.

3. Peter likens apostates to a dog returning to its vomit (2 Peter 2:22, quoting Proverbs 26:11), underscoring recidivism into sin.


Immediate Context in Revelation 22

Revelation 21–22 depicts the New Jerusalem where only the redeemed may enter (22:14), contrasted with those “outside” (22:15). John itemizes six categories; “dogs” heads the list, functioning as an umbrella term for morally and doctrinally impure people. The sequence moves from general (dogs) to specific (sorcerers, sexually immoral, murderers, idolaters, liars), a literary device that frames “dogs” as a summary label for covenant outsiders.


Theological Significance

1. Moral Uncleanliness: As the Law excluded unclean animals from sacrificial worship, so Revelation excludes unregenerate sinners from eschatological fellowship.

2. Boundary-Marker: The contrast between “blessed…enter the city” (22:14) and “outside are the dogs” (22:15) illustrates the irreversible divide fixed by final judgment.

3. Christological Fulfillment: Jesus’ atonement provides cleansing from the defilement typified by “dogs.” Those washed in the Lamb’s blood (Revelation 7:14) become citizens inside the gates.


Connections to Deuteronomy 23:18

Given Deuteronomy’s linkage of “dog” with male prostitution, many commentators see an allusion to sexual perversion in Revelation 22:15. This is reinforced by the pairing with “sexually immoral” (πόρνοι). The composite term thus covers both deviant sexuality and broader covenant infidelity.


Relational and Behavioral Dimensions

Behavioral science affirms that habitual lying, violence, and sexual exploitation diminish empathy and community trust—traits mirrored in Revelation’s catalogue. Scripture aligns ethical dysfunction with spiritual separation; the metaphoric “dog” denotes both pathology and its eternal consequence.


Practical Application

Believers are called to discern those who display the traits of “dogs” (Philippians 3:2) yet still offer them the gospel (1 Corinthians 6:11). The passage warns covenant members not to relapse into “dog-like” behavior, for “nothing unclean will ever enter it” (Revelation 21:27).


Summary Definition

In Revelation 22:15, “dogs” functions as a comprehensive metaphor for the morally impure, doctrinally corrupt, and spiritually unregenerate who remain excluded from the eternal city. Rooted in Jewish purity laws, prophetic invective, and New Testament polemic, the term underscores the finality of judgment and the necessity of cleansing through Christ.
