"Canticorum Jubilo" is a choral excerpt from George Frideric Handel's oratorio "Joshua" (HWV 64), composed in 1747 and premiered in 1748, depicting the biblical story of Joshua's conquest of Canaan. Handel (1685–1759) was a German-British Baroque composer renowned for his oratorios, operas, and choral music, and "Joshua" stands as one of his later but significant oratorio works.

"Worthy Is the Lamb" is the majestic closing chorus of Handel's oratorio Messiah (HWV 56, 1741), leading directly into the final "Amen" chorus and serving as the culminating statement of the entire work. Handel composed Messiah in just 24 days, and this full-score edition captures the grandeur of the choral and orchestral writing that has made it one of the most performed choral works in history.
