Shared ground
Psalm 120:4 is a poetic answer to the question raised in Psalm 120:3 about what a “deceitful tongue” deserves. It does not narrate an incident; it delivers a verdict-like picture.
The verse uses two linked images: “sharp arrows” shot by a “mighty” warrior (warrior), and “coals of juniper/broom.” Together they communicate a fitting return for harmful speech: damage that is deliberate, painful, and not easily shrugged off.
Where interpretation differs
Some interpreters read the images mainly as punishment that will come upon the liar (whether by God’s judgment, human agents, or both). In this reading, the “arrows” and “coals” are what the deceiver receives.
Others read the images as describing what the deceitful tongue itself is like and does—piercing and burning. In that case, the verse is less about future payback and more about the destructive character of deceit.
A smaller point of difference is what plant is meant by “juniper”: many argue it is the broom shrub (a desert plant that makes long-burning charcoal), while some render it as “juniper tree.” Either way, the point is extremely hot, lasting coals.
Why the disagreement exists
The verse is highly compressed. It does not explicitly say who administers the recompense, and the imagery (weapons and fire) can work either as (1) judgment imagery or (2) a metaphor for speech’s harm. Translation choices also affect how concrete “juniper” sounds and what readers picture.
What this passage clearly contributes
Explicitly, the text supplies vivid images—sharpened arrows and enduring coals—as the “answer” to what the deceiver gets back. By inference, the passage strengthens a moral logic of fitting recompense: corrosive words are treated as seriously destructive, and the outcome for such speech is pictured as targeted and lasting harm rather than a minor consequence.
