David HaMelech says: “The sound of rejoicing and salvation is in the tents of the righteous... Open for me the gates of righteousness, I will enter them and thank G-d” (T’hilim 118:15, 19). The word “ohel” [“tent”] signifies a non-permanent dwelling. A “bayis” [house] is a permanent dwelling. Rabbi Frand explains that the reason there is rejoicing and salvation, enjoyment and contentment, in the lives of the righteous is that their existence in this world is like that of a tent – temporary. In this world, we have work to do and mitzvos that must be performed. But our physical surroundings are only temporary dwellings – tents.
