LEV762 It is a positive commandment to have a reverent fear of the Sanctuary as Scripture says, and reverence My sanctuary [this verse]. Now, our synagogues and houses of Torah study are called "a little sanctuaries", as Scripture states, yet have I been to them as a little sanctuary (Yehezkel 11:16). We have to beware in them from any frivolous laughter or levity, or any idle talk. No calculations are to be reckoned there, nor are they to be slept in. Their holiness is very severe.
