This question is used to imply that Yahweh's punishment of Edom would be worse than what thieves would do when they steal. This can be stated explicitly. Alternate translation: "If thieves came to you ... they would only steal as much as they needed, but I will take everything from you!" (See: [[rc://en/ta/man/translate/figs-rquestion]] and [[rc://en/ta/man/translate/figs-explicit]])
These two phrases mean the same thing and are used to emphasize people who steal. They can be combined. Alternate translation: "When thieves break into someone's house during the night" (See: [[rc://en/ta/man/translate/figs-hendiadys]])
Yahweh adds this phrase in the middle of another sentence to express that the punishment of Edom is shocking. Alternate translation: "you are completely destroyed!"
This question is used to imply that Yahweh's punishment of Edom would be more thorough than what grape gatherers would do when they harvest grapes. This can be stated explicitly.

(See: [[rc://en/ta/man/translate/figs-rquestion]] and [[rc://en/ta/man/translate/figs-explicit]])
