The uploaded image is upside-down.
It is the scroll (presumably this one was kept as a spare) which is placed inside a Mezuzah:
https://en.wikipedia.org/wiki/Mezuzah
Jewish people are commanded to place a little box - Mezuzah, upon every door post of their home, and this scroll is placed within the Mezuzah.
You can see a clearer Mezuzah scroll here (correct way up) - the only way I could access a copy was on an advertisement, but the reason I have provided this link is only so you can compare the two scrolls - the hand-written wording in Hebrew being of course, identical (click the image to enlarge it):
