Are all Blacks Hebrew Israelite?
No, some blacks are of a non Israelite ancestry. For example some are sons and daughters of Mitzrayim “Egyptians” who were also scattered among the nations. (Ezk 29:12;30:23;30:26) However, if you are experiencing the Israelite curse according to Deut 28 and many other scriptures then you are more than likely a Hebrew Israelite.
