their brother Benjamin

This speaks of the tribe of Benjamin as if it were Israel's brother to show their closeness to the tribe. Alternate translation: "the surviving Benjamites" (See: rc://en/ta/man/jit/figs-metaphor)

one tribe has been cut off from Israel

The destruction of the tribe of Benjamin is spoken of as if it had been cut off from Israel by a knife. This was an exaggeration because 600 men were still left. However, the women of Benjamin had been killed, so the future of the tribe was in question. Alternate translation: "one tribe has been removed" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-hyperbole)
