Topical Lexicon
Root concept and semantic range

Strong’s Greek 1387 expresses the action of luring or ensnaring by treachery. It portrays speech that sets a hidden hook—language crafted to mislead, manipulate, or betray confidence. The verb pictures deliberate, calculated guile rather than an impulsive falsehood.

Old Testament background (LXX)

The Septuagint employs the root in poetic and prophetic texts to expose the moral rot that accompanies covenant violation. Psalm 5:9 (LXX 5:10) laments, “with their tongues they deceived” (ἐδολιοῦσαν), setting the pattern Paul will later cite. Similar imagery appears in Jeremiah 9 where deceit saturates Judah’s everyday speech. Throughout the LXX, δολιόω unveils a heart posture intent on exploiting neighbor and God alike.

New Testament usage

Romans 3:13 contains the verb’s lone New Testament occurrence:

“Their throats are open graves; their tongues practice deceit”.

Paul inserts the quotation in a catena of Old Testament testimonies (Romans 3:10-18) to prove that both Jew and Gentile stand guilty under sin. The perfect harmony between Psalmist and Apostle underscores Scripture’s unified witness to human depravity.

Theological significance

1. Sin’s universality: δολιόω crowns a list of bodily members (throat, tongue, lips, mouth, feet) recruited into rebellion, illustrating how comprehensive corruption is.
2. Heart-mouth connection: Deceitful speech reveals an inner disposition alienated from truth (Matthew 12:34).
3. Need for redemption: Romans 3 pivots from indictment (vv. 9-20) to justification in Christ (vv. 21-26). The exposure of δολιόω prepares the conscience for grace.

Practical implications for ministry today

• Guarded speech: James warns, “the tongue…sets the whole course of one’s life on fire” (James 3:6). Believers pursue transparent, edifying communication (Ephesians 4:25, 29).
• Discernment: Church leaders must test teaching and motives (1 Thessalonians 5:21) lest doctrinal deceit infiltrate the flock.
• Gospel counseling: Confronting habitual deceit requires both repentance and renewal of the mind (Romans 12:2), anchored in the Spirit of truth (John 16:13).

Related terms and concepts

ἀπάτη (deception), δόλος (guile), ψεύδομαι (to lie). Together they form a biblical theology of falsehood that contrasts sharply with ἀλήθεια (truth) embodied in Jesus Christ (John 14:6).

Illustrative examples in Church history

• Early apologists like Justin Martyr denounced pagan philosophers who “practiced deceit” through sophistry, echoing Romans 3:13.
• Reformers cited the verse against ecclesiastical corruption, urging a return to Scripture’s plain truth.

Homiletical pointers

1. Exposition: Walk the congregation through Romans 3:10-18, highlighting how δολιόω fits Paul’s anatomy of sin.
2. Illustration: Use the metaphor of fishing with hidden barbs to depict deceitful speech.
3. Application: Challenge listeners to inventory their words from the past week; invite specific repentance and Spirit-empowered change.

Summary

Strong’s Greek 1387 confronts the believer with the sobering reality that the tongue can become an instrument of treachery. Its solitary appearance in Romans 3:13, buttressed by rich Old Testament precedent, serves the grand redemptive purpose of exposing sin so that grace may abound.
