The mezuzot has a passage on it that I found interesting.
The commandment to place mezuzot on the doorposts of our houses is derived from Deut. 6:4-9, a passage commonly known as the Shema. In that passage, God commands us to keep His words constantly in our minds and in our hearts, by writing them on the mezuzot or doorposts of our house. This means that God wants his people to remember what he tells them by telling them to leave a reminder for themselves at the doorposts of their houses.
