Kol Meqadesh Shevi'i

"Kol Meqadesh Shevi'i" is an ancient hymn, possibly composed by Moses ben Kalonymus. The hymn is first found in Add MS 27200, a 13th-century copy of the 11th-century Machzor Vitry, as the first hymn for the Sabbath; because the section with hymns does not appear in superior copies of Machzor Vitry, it is likely a later addition. Over the generations it has been set to many tunes. Ashkenazi Jews customarily sing it on Sabbath Eve, usually omitting the last stanza (see below).

Each stanza has four lines; the first three continue the acrostic and the fourth is a Biblical verse or verset.
