# Seal up

People in John's day would write a message on a scroll and then seal the scroll so that only the person whom the writers wanted to open it were able to open it. This is a metaphor for keeping something secret. Alternate translation: "Keep secret" (See: [[rc://en/ta/man/jit/figs-metaphor]])
