The greatly enlarged work set to a French libretto was composed with so much additional music, including a substantial ballet, as to warrant a new title, Moïse et Pharaon, ou Le passage de la Mer Rouge ( Moses and Pharaoh, or The Crossing of the Red Sea) ( pronounced ), and was seen to be a separate and new opera alongside its Naples progenitor. Rossini slightly revised the opera in 1819, when he introduced Moses' prayer-aria "Dal tuo stellato soglio", which became one of the most popular opera pieces of the day and which inspired a set of variations for violin and piano by Niccolò Paganini. Billed in 1818 as an azione tragico-sacra, the sacred drama with some features of the oratorio circumvented proscriptions of secular dramatic performances during Lent. The 1818 opera opens as the plague of darkness is dispelled by Moses' prayer, and it ends with the spectacle of the parting of the Red Sea and the drowning of Pharaoh's host, which "elicited howls of derision" at the clumsy machinery of its staging at the premiere, though the opera surmounted its technical failings and was a hit. The opera was loosely based on the Exodus from Egypt of the Israelites, led by Moses, rendered agreeable to the opera stage by introducing a love theme, in which the Pharaoh's son Amenophis plans to prevent their departure, since he loves the Israelite Anaïs. And it's not just me who says that, but the great Rossini himself. Mosè in Egitto is a wonderful opera, but it remains very much a mere sketch for Moïse et Pharaon. I prefer it because Rossini himself preferred it. Riccardo Muti and many scholars consider Moïse et Pharaon, along with Guillaume Tell, to be among Rossini's greatest achievements: The première took place in the Salle Le Peletier of the Paris Opera on 26 March that year. This was written by Luigi Balocchi and Victor-Joseph Étienne de Jouy. In 1827 Rossini revised and greatly enlarged the work to a four-act French libretto: Moïse et Pharaon, ou Le passage de la Mer Rouge ( pronounced " Moses and Pharaoh, or The Crossing of the Red Sea").

It premièred on 5 March 1818 at the recently reconstructed Teatro San Carlo in Naples, Italy. Mosè in Egitto ( Italian: " Moses in Egypt") is a three-act opera written by Gioachino Rossini to an Italian libretto by Andrea Leone Tottola, which was based on a 1760 play by Francesco Ringhieri, L'Osiride.
