 The theme of the shekhinah as the Sabbath Bride recurs in the writings and songs of 16th century Kabbalist, Isaac Luria.The "Asader Bishvachin" song, written in Aramaic by Luria (his name appears as an acrostic of each line) and sung at the evening meal of Shabbat is an example of this.The song appears in particular in many siddurs in the section following Friday night prayers and in some Shabbat song books
