According to Wikipedia, the Songs of Ascent are "characterized by brevity, by a key-word, by epanaphora [i.e., repetition], and by their epigrammatic style.... " Epigrams are defined as "brief, interesting, memorable ... sometimes surprising or satirical.... The presence of wit or sarcasm tends to distinguish non-poetic epigrams from aphorisms and adages, which may lack them."
Which portions of the Songs of Ascents might be considered epigrammatic, and what spiritual / religious function might this serve?
