Hang a mezuzah on the “doorposts” of your house. Perhaps you have heard the word or very often seen one. The word Mezuzah is often used to refer to just the case. So, let’s start off by saying that the Mezuzah has two parts it’s a case that protects the Shema that is inside of the case. Two parts, the written text of the Shema and a case to protect the written Shema. Just putting up the case isn’t what I’m talking about. Although you can certainly collect Mezuzah cases and display them in your home. I have a neat collection of Mezuzah case mounted on glass doors from a break front.
