A “Mezuah” is a small parchment scroll, made from the skin of a clean animal, affixed to the right doorpost of the entrance to inhabitable rooms of Jewish homes.
The scroll contains the two passages of the Torah. (Deuteronomy 6:4-9 and 11:13-21) which mention the commandment of Mezuah : “you shall write them upon the doorposts of your home and your gates”.
These passages are the first two portions of the “shema” Prayer, and affirm God's existence and authority. The text must be written in accordance with the Halakhic requirements. Such as how the parchment must be processed, how the letter must be formed, and many other details. The parchment is generally rolled up and inserted into a case which is affixed to the doorpost, one-third down, slanting inward.
