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.

Passover commemorates the story of the Exodus, in which the ancient Israelites were freed from slavery in Egypt. Passover begins on the 15th day of the month of Nisan in the Jewish calendar, which is in spring in the Northern Hemisphere, and is celebrated for seven or eight days. It is one of the most widely observed Jewish holidays.

The Israelites were instructed to mark the doorposts of their homes with the blood of a slaughtered spring lamb (“pascal lamb”) and, upon seeing this, the spirit of the Lord knew to pass-over the first-born in these homes, hence the English name of the holiday.
Selective readings for the Passover season are read throughout Hebraic households, communities, and congregations during this special time to keep a remembrance among these said communities for generations to come.
