The Ethnicity of the Egyptians is the key to understanding the Blackness of the Hebrews and surrounding nations.
The genealogical chart in Genesis 10 lists Ham/Khem as the father of Africans and from Africans came Egypt, Babylon, Persia, Kushites/Nubians. The proper word Khem/Kam means Black. These intermarried with the Hebrews and so produce the Hebrew nation of Israel.
That is the Jewish line itself was that of Black/African Canaanite woman named Tamar (Genesis 38:1-5),
The Canaanites were descendants of Ham/Khem (Gen. 10:6). Again, the word means Black.
Abraham beget the Arab line through an Egyptian woman Hagar. She then picked a Egyptian wife for her son Ishmael who would father the original Black/African Arabs (Genesis 16; 21:21). The original arabs were Black/African.
The Egyptians are identified in the Bible as Hamites/Khemites (Psalm 106:21-22; 78:51; 105:27).
Scripture states, “Is rael sojourned in Egypt the land of HAM/KHEM’ Psalm 78:51.
The establishment of the Hebrew nation is told in the Pentateuch or first five books of the Bible also called the Torah. Throughout the first five books we see Hebrews intermarrying with Black/African Egyptians, Canaanites, Kushites all listed under descendants of HAM/KHEM (Genesis 10:6).
