Excerpts:
“Shem was the ancestor of all the sons of Eber” (Genesis 10:21), and this is important because the word Eber is the origin of the Hebrew word for “Hebrew.” The word Shem means “name,” which implies that Noah expected this son’s name to become great. He was right—the modern words Semitic and Semite are derived from Shem’s name. The Bible records that Shem had five sons: Elam, Ashur, Arphaxad, Lud, and Aram (Genesis 10:22). Shem lived to be 600 years of age (Genesis 11:10–11) and became the ancestor of the Semitic peoples (Genesis 10:1, 21–31). Abraham, a descendant of Shem, is the first person in the Bible who is referred to as a “Hebrew” (Genesis 14:13).
Noah blessed Shem above his brothers (Genesis 9:26–27), and it was through Shem that the promised seed destined to crush Satan came (Genesis 3:15). That seed is traced back to Adam’s son Seth (Genesis 5:1–32), through Shem, and on to Abraham, Judah, and David, leading all the way to Christ (Luke 3:36).
....
Ham, the youngest of the Noah’s three sons, had four sons: Cush, Mizraim (Hebrew for “Egypt”), Put, and Canaan (Genesis 10:6; 1 Chronicles 1:8). Egypt was later called the “land of Ham” (Psalm 78:51; 105:23; 106:22).
The Hamitic peoples are shown in Genesis 10:6–20 as becoming a godless and worldly power. It was the land of Palestine that was assigned to Ham’s son, Canaan, and for centuries it was under the control of the Egyptians. Ham is the father of the Arabians, Canaanites, and Africans, including the Egyptians. Due to Ham’s sin against his father (Genesis 9:20–25), Noah cursed Canaan, saying Canaan would be a servant to Shem (Genesis 9:26). This was fulfilled centuries later when the Israelites entered the land of Canaan and subdued the inhabitants of that land (1 Kings 9:20–21).
