Two Sources for Basic Commentary
—Rabbi Benjamin Segal offers an analysis of Psalm 27 in its biblical-literary context and discusses the unity of psalm, behind its apparently disparate set of emotions. The very readable series from Schechter Institute in Philadelphia also includes complete text of each psalm in English and Hebrew. This commentary includes a note on the use of Psalm 27 in Elul and the Days of Awe. [UPDATE 2017: Sadly, this on-line resource appears to be gone; Segal’s A New Psalm: The Psalms as Literature is now published by Geffen Books.]
—Machzor Lev Shalem offers explanatory notes as well as a few thoughts on Psalm 27 in the penitential season. Unfortunately, the Rabbinical Assembly’s link to this material, previously offered here, is no longer public. Instead, a few notes are shared in More Exploring Psalm 27 (2 of 4). (Here is the machzor’s own website.) The Kol Nidrei sample pages include Zelda’s poem on “that strange night,” inspiration for this essay during Elul 5772.
