Virga Jesse floruit
Traditional medieval text, based on Isaiah:11, stating that Jesus belongs to David's lineage (Jesse being King David's father). In the Tridentine Rite it is assigned as the Alleluia verse for the Feast of the Annunciation when it falls in Eastertide instead of Lent. More commonly it is heard at Votive Masses.
The early E-flat version of J. S. Bach's *Magnificat BWV 243 has a fragmentary duet for soprano and bass, "Virga Jesse floruit, Emanuel noster apparuit", unrelated but for the incipit.
