I do not know whether any Jews actually sing this Passover hymn (_Addir hu_) on other occasions during the year. Murray’s Palestine Handbook asserts that “the lamentations are taken from the 79th Psalm,” a statement which points to the same source as that relied on by Baedeker. The latter gives two forms, of which the first runs thus: _Leader_: For the palace that lies desolate: _Response_: We sit in solitude and mourn. _Leader_: For the palace that is destroyed: _Response_: We sit, etc. _Leader_: For the walls that are overthrown: _Response_: We sit, etc. _Leader_: For our majesty that is departed: _Response_: We sit, etc. _Leader_: For our great men who lie dead: _Response_: We sit, etc. _Leader_: For the precious stones that are burned: _Response_: We sit, etc. _Leader_: For the priests who have stumbled: _Response_: We sit, etc. _Leader_: For our kings who have despised Him: _Response_: We sit, etc. Whence did the compiler of Baedeker derive this? From the Karaites. If one turns to the fourth volume of the Karaite liturgy, published in Vienna in 1854, page 208, this litany is to be found. It is part of a very long series of prayers (which include, on page 212, the passage which, in Baedeker, follows the one cited above). Psalm 79, referred to in Murray, appears in the same Karaite book on page 206. The selections are a tiny fraction of the whole. The Karaite prayers are always extremely long. Thus, their marriage service fills eleven large, closely printed sides. The Jerusalem prayers are even more elaborate. As the pilgrim starts from home for the Holy City, the congregation turns out to give him a send off, reciting _sixteen_ Psalms as a supplication for his protection, and other _fourteen_ Psalms in praise of Jerusalem. He then proceeds on his way. When he arrives at the city, as far off as the distance at which a man can recognize his fellow, he rends his garments and mourns as for a lost first-born. He then recites parts of the Lamentations, and enough Psalms and Selihot to occupy another ten pages. Some of us complain of the length of our prayers; when we look at the weary mass of the Karaite liturgy, we stand amazed at our own moderation.
