This TBB a cappella arrangement of the well-known text Veni, Veni Emmanuel is an example of music used by both Old and New Testament believers. With text traced back to the Psalteriolum Cantionum Catholicarum (Cologne, 1710), the original lyrics are drawn primarily from the Book of Isaiah in the Old Testament. For Christians, it is used in the Advent season, specifically on the first two Sundays of Advent to set the tone of expectation for the coming of the savior. In Judaism, it may also be used as a harbinger of the savior yet to come, without the restriction of the Advent season.
