This can be stated as an indirect quotation. Alternate translation: "I thought they would surely fear me and accept correction so that they would not be cut off from their homes by all that I have planned to do to them." (See: [[rc://en/ta/man/translate/figs-quotations]])
Here "cut off" is an idiom that means to be removed. This can be stated in active form. Alternate translation: "so that I will not remove you from your homes" (See: [[rc://en/ta/man/translate/figs-idiom]] and [[rc://en/ta/man/translate/figs-activepassive]])
