Have the gates of death been revealed to you

Death is spoken of as if it were a city that had gates through which people enter into it. This can be expressed in active form. AT: "Has anyone shown the gates of death to you" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-activepassive)

the shadow of death

See how you translated this in Job 3:5.
