Deborah (HWV 51) is an oratorio by George Frideric Handel. It was one of Handel's early oratorios in English and was based on a libretto by Samuel Humphreys. It received its premiere performance at the King's Theatre in London on 17 March 1733.
The story of the oratorio takes place in a single day and is based on the Biblical stories found in 4 and 5 Judges. The Israelites have been subjugated for 20 years by the Canaanites, when the prophetess Deborah foretells the death of the Canaanite commander Sisera at the hands of a woman. The Israelite commander Barak leads them into battle against the Canaanites. The Israelites are victorious and a woman, Jael, assassinates Sisera as he sleeps in her tent.
Handel reused music from numerous previous compositions for Deborah. The work, with large choruses and grand orchestral effects, was very successful and was revived by Handel in subsequent years.
By 1733, Handel had spent nearly twenty years composing and presenting seasons of Italian opera in London. The great success of Esther the previous year had shown Handel that there was potential for further works of "Sacred Drama", performed in concert form in English. Deborah reuses much music Handel had previously composed, including passages from the Brockes Passion, Il trionfo del tempo e del disinganno,the Dixit Dominus, and others.Deborah was performed as part of Handel's season at the King's Theatre in 1733, with the stars of the Italian opera singing in English, and the composer / impresario was so confident of the work's success that he doubled the price of admission for the first performance, causing some resentment and comment in the press. A feature of the work is massive choruses, some in eight parts rather than the usual four, and grandiose orchestral effects featuring trumpets and drums. One witness to the first performances noted "It is very magnificent, near a hundred performers,among whom about twenty-five singers" while another remarked "'tis excessive noisy, a vast number of voices and instruments, who all perform at a time."Deborah achieved considerable popularity and was revived by Handel in a number of subsequent seasons.
