A time in the future when bad things will happen to the people is spoken of as if those days will attack the people. The word "they" refers to their enemies. Alternate translation: "There will be a time when your enemies will take you away with hooks" (See: [[rc://en/ta/man/jit/figs-metaphor]])
These two phrases mean basically the same thing and emphasize that the enemy will capture the people like people catch fish. Alternate translation: "they will capture you as people capture animals, and they take you away" or "they will defeat you and cruelly force you to go away with them" (See: [[rc://en/ta/man/jit/figs-parallelism]] and [[rc://en/ta/man/jit/figs-metaphor]])
