Greetings in the name of His & Her Imperial Majesties Qedamawi Haile Sellassie I & Itege Menen Asfaw,
Ras Tafari Renaissance writes to give perspective to the Hebraic remembrance of the Passover. In modern Judaism, it is known by the Hebrew term as Pesach-פֶּסַח. Jewish traditions celebrate the liberation from slavery in Egypt approx., 3,300 yrs ago by God; during the time of the Pharaohs, and their freedom as a nation under the leadership of. But, from the Ethiopian-Hebraic perspective, the liberation came from within a spiritual, socio-political, and religious viewpoints between Northern Egypt(Lower Egypt) & Southern Egypt(Upper Egypt).

Passover is considered apart of the Shalosh Regalim, or the main festivals of Israel’s commemoration to God. The day commences on the afternoon of the Hebraic, 14th of the month of Nisan.
The narrative of the Exodus from the Scriptures, [Exo. 23: 15], gives the overlay of the children of Israel story in Rgypt.
