When passing a mezuzah, Jews are traditionally encouraged to touch it with their hand or an object, and then kiss their fingers as a sign of respect and remembrance of God's commandments.

The Bible contains a commandment to "write these words on the doorposts of your homes, and on your gates." Many Jews keep this commandment by hanging the text of "these words" in the form of a little scroll in an ornamental case on the doorpost of their front door (and sometimes on interior doors). The scroll and case are usually called a mezuzah (the word just means doorpost). There's a brief blessing to say before hanging a mezuzah, and this blessing, plus the hanging of a mezuzah, frequently serves as the formal dedication of a new Jewish home.
