Jews typically place a mezuzah on their doorposts: a small case that holds a handwritten parchment scroll with Jewish prayers and verses, usually attached to the right side of the doorway as you enter. It serves as a religious reminder of faith and Jewish identity.

What it is

A mezuzah is not just the case on the outside; the important part is the scroll inside, which is handwritten by a trained scribe and placed on the doorpost in Jewish homes. Many Jews also touch it when entering or leaving as a sign of reverence.

Why it’s used

The practice comes from a commandment in the Torah to write these words “on the doorposts of your house and on your gates,” especially in Deuteronomy 6:9. In practice, it marks a home as Jewish and reminds residents of their values and traditions.

Small note

Placement details can vary a bit by community, but the mezuzah is the standard answer to your question.
