Summary of passage: Genealogy of Shem, Ham, and Japheth (Noah’s sons).
The sons of Japheth were maritime peoples and spread out with their own language.
Cush was the son of Ham who was the father of Nimrod who grew to be a mighty warrior and hunter on earth. The first centers of his kingdom were Babylon, Erech, Akkad, and Calneh in Shinar. Then Cush went to Assyria to build Ninevah, Rehoboth, Ir, Calah, and Resen.
Later, the Canaanites scattered, pushing out the borders from Sidon to Gaza and Lasha.
Shem’s ancestors lived in the eastern hill country from Mesha to Sephar.
10a) Cush was Nimrod’s father and Nimrod’s grandfather was Ham. He was a mighty warrior and hunter on earth. He ruled a kingdom that included Babylon, Erech, Akkad and Calneh. He then conquered Assyria and established more cities.
Fun fact: Nimrod’s name means “let us rebel”.
b) Bad. “The mighty hunter before the Lord” is not a hunter of animals but of humans. This is not a compliment. This is also the first use of the word “kingdom” in the bible, which implies he consolidated the peoples and probably in a ruthless manner. Ultimately, he relied on his own strength instead of God’s.
11) “because in his time the earth was divided”
12) Uz and Jobab. Job came from the region of Uz and Jobab may be the one we know as Job.
13) Like most lists of names and genealogies in the Bible, it is used to chronicle the line of Jesus and collaborate God’s words to man (who always seems to need evidence). Also, it explains how the world was re-populated after the flood and who and how founded the nations of the earth.
Conclusions: Keep in mind the distribution of peoples: Japheth was the father of the western Europeans, the Medes, and the Greeks. Ham was the father of Africans (Egypt and Ethiopia) and the far East (including Babylon and Canaan). Shem was the father of the Persians, the Assyrians, the Hebrews (Abram), and Asia Minor.
