Many communities recite a series of poems interwoven with the Amidah on Purim. These poems, known as the “krovets,” were written by Elazar b. Rabbi Kalir, the greatest of the early paytanim. But lesser known than the krovets for Purim are the krovets for Tisha b’Av, written as well by Elazar b. Rabbi Kalir. A fine example of Elazar’s intricate poetry, the krovets for Tisha b’Av is rife with Biblical citations, finally culminating with the prayer for Jerusalem. Each stanza begins with five tightly rhymed lines beginning with a constant א followed by a quintuple half-acrostic on the second letter, then a poetic volta on the word אֵיכָה, followed by a Biblical citation, a verse starting with the last word in the citation, a letter from Elazar’s name, and a final Biblical citation. The krovets for Tisha b’Av is meant to be part of the morning service, tied into the cantorial repetition for Tisha b’Av. . . .

The poetic genre known as ḳerovot, brief poems woven throughout the repetition of the weekday Amidah, is nowadays most closely associated with Elazar biRabbi Qallir’s Purim “Qrovetz“, a majestically interwoven piece of piyyut if ever there was one. But there are many other ḳerovot that have historically been recited, and this one is by the same author! The weekday qerovot cycle for Ḥanukkah, retelling the story of the Greek oppression using intricate poetic language. Included within is a qedushtah that instructs us on some of the halakhic requirements for the Ḥanukkah lights. . . .
