Moses describes the curses as a person who would attack them by surprise. See how you translated these words in [Deuteronomy 28:15](../28/15.md). Alternate translation: "Yahweh will curse him with the curses written in this book in ways that will completely surprise him" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-personification]])
This means God will completely destroy the person and his family. In the future people will not remember him. A similar phrase appears in [Deuteronomy 7:24](../07/24.md).
