Wall to Wall

Prepared for print by Faigy Peritzman

When visiting Israel, I noticed many apartments have a big unpainted square on the wall, a zeicher l’Churban. I rarely see that in my own community. Is this a halachah or a sensitivity?

Shulchan Aruch rules that when one builds a home, he needs to leave a square amah (approx. 22 x 22 inches) in an unfinished state as a zeicher l’Churban, a token reminder that the Beis Hamikdash is yet to be rebuilt. In the past, this halachah wasn’t widely observed, since most Jews didn’t build their homes from scratch, but purchased second-hand homes built by non-Jews. Nowadays, when there are many Jewish builders (especially in Eretz Yisrael), more and more people are observing this halachah in the way it’s supposed to be kept.

We’re doing renovations and closing a wall in our home to make another bedroom. I was surprised when my neighbor told me I need to leave a small hole open in the new wall. Is this halachah or superstition?

It’s neither a halachah nor a superstition, but advice from Rav Yehudah Hachasid, who warns homeowners not to completely close up any opening, since that will “block the sheidim from exiting” and may harm the people who live there. As with any advisory of Rav Yehudah Hachasid, which aren’t meant to be binding halachos but recommendations, some people follow them strictly, others follow them in part, and others don’t follow them at all. In your case, there’s an additional reason for leniency, since Rav Shlomo Zalman Auerbach is quoted as ruling (orally) that this applies only to an external door or window, not an internal one. Other poskim suggest that if you close up a window or door, but replace it with alternative exits, then the advice can be disregarded.

We have a curved archway between our dining room and living room. Does this arch need a mezuzah?

If the side posts of the arch are ten tafachim (about 35-38 inches) tall before they begin to arch, then the archway is considered a standard opening and requires a mezuzah.

I have several large-framed pictures on our dining room wall. Recently on Shabbos, one of the grandchildren knocked a picture so that it was hanging very askew. I wanted to straighten it, but my son-in-law said that isn’t permitted on Shabbos. Why?

Your son-in-law was quoting a ruling of the Chazon Ish, who maintained that a picture (or a clock) hanging on the wall is muktzeh and may not be moved on Shabbos for any reason. The Chazon Ish explains that since a picture hung on the wall is consigned to be in a designated place and isn’t meant to be moved, it’s considered a form of muktzeh to touch it, similar to muktzeh machmas chisaron kis (a class of muktzeh which includes fragile or delicate items which aren’t moved for fear of damaging them). Note, however, that many other poskim, including Rav Moshe Feinstein, disagree and don’t consider a picture or a clock hanging on a wall to be muktzeh. In their view, those items aren’t considered “consigned to a dedicated place,” but are hung on the wall for the purpose of displaying them.
