Destruction is spoken of as if it was a dangerous animal that would suddenly attack them. Alternate translation: "Let them be destroyed suddenly" or "Let them be surprised because you destroy them suddenly" (See: [[rc://en/ta/man/jit/figs-personification]])
The schemes of the wicked are spoken of as if they were a net that they place to catch the writer. Alternate translation: "the net that they placed in order to capture me like an animal and harm me" (See: [[rc://en/ta/man/jit/figs-metaphor]])
This is the same metaphor as in verse 7. The net is intended to catch the writer. Alternate translation: "Let them fall into the pit that they dug for me" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-explicit]])
The abstract noun "destruction" can be stated as a verb. Alternate translation: "so that they will be destroyed" or "that is how you should destroy them" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
