Destroying something is often spoken of as it were cutting it off from something else. Alternate translation: "May Yahweh destroy anyone in the tents of Jacob who" or "May Yahweh kill anyone in the community of Israel who" (See: [[rc://en/ta/man/jit/figs-metaphor]])
Here "Jacob" stands for all the Israelites, because Jacob was one of the patriarchs from whom the Israelites were descended. (See: [[rc://en/ta/man/jit/figs-metonymy]])
