Shared ground
These verses continue Psalm 58’s rapid-fire images of the wicked being stopped decisively. The speaker is not describing a slow moral turnaround but asking for a quick end to the opponents’ power and plans.
The pictures all push the same idea: disappearance and interruption. The “snail” image conveys something that dwindles as it moves; the “stillborn child” conveys a life and future cut off before it is ever seen. The cooking scene says the removal happens so fast that the pot does not even warm up before God “sweeps away” what is happening.
Where interpretation differs (only where needed)
1) What exactly “a melting snail” means. Some take it as a common observation: the snail seems to waste away as it goes (leaving a trail behind). Others hear it as deliberate exaggeration for effect: not a claim about biology, but a vivid way to say “let them vanish.”
2) What “green and the burning alike” refers to. Many read it as stages of the thorn fuel: whether the brush is still fresh (“green”) or already burning, God ends the cooking before it really begins. Others read it more broadly as “in every condition,” stressing total removal rather than pinpointing fuel stages.
3) Who “your pots” points to. Some hear it as addressing the wicked (their pots, their cooking, their schemes). Others hear it as a general “your,” closer to “the pots people use,” without changing the main point: the outcome is cut short.
Why the disagreement exists
The Hebrew is compact and image-heavy, and the metaphors come from everyday scenes that can be heard more than one way. Also, verse 9 shifts quickly from kitchen imagery to God’s action (“He will sweep away”), so interpreters differ on how tightly each phrase maps onto the scene.
What this passage clearly contributes
Textually, the psalm openly asks for the enemies’ swift removal (snail; stillbirth; pot interrupted) and presents God as the one who can do it (“He will sweep away”). Theologically inferred from that, the verses contribute to the Psalms’ portrayal of God as able to end violent injustice abruptly, not merely restrain it gradually, and as able to cut off the “future” of wrongdoing before it becomes publicly established (the “not seeing the sun” image).
