The Feast of Unleavened Bread is the first of the Pilgrimage Feasts where all Israelites (including all grafted in by faith in Yeshua Messiah) are commanded to appear before YeHoVaH, our Elohim, at the place He will choose. The Nation of Israel was established in Egypt, but became functional as a nation after the Exodus from Egypt.
In the teaching, A Nation is Born, we will look at the development of Israel as a nation, its birth, and the Commandments required to be observed in perpetuity during The Feast of Unleavened Bread.
