make one's hair stand on end, to

To terrify. The Book of Job (4:14–15) states, “Fear came upon me . . . and the hair of my flesh stood up.” The allusion here is to the goose pimples aroused by fear (or cold), the raised bumps on the skin that cause the hairs around them to stand up. Centuries later this gave rise to the adjective hair-raising, a synonym for terrifying.
