I think these genealogies are just so interesting because they are the second start of all civilization! All of us came from these three guys!
1) Japheth was the eldest, and his children made up the isles of the Gentiles as they became divided by land, tongue, family, and nation.
Japheth's children were GOMER, Magog, Madai, JAVAN, Tubal, Meshech, and Tiras.
Gomer's children were Ashkenaz, Riphath, Togarmah
Javan's (Gomer's brother) children wer Elishah, Tarshish, Kittim, and Dodanim.
2) Ham was the middle son, who looked on his father's nakedness and received the curse of servitude to his brethren.
Ham's children were Cush, Mizraim, Phut, and Canaan
Canaan's sons mentioned by name are Sidon and Heth. After that, his descendants are detailed as peoples: the Jebusite, the Amorite, the Girgasite, the Hivite, the Arkite, the Sinite, the Arvadite, the Zemarite, and the Hamathite. Gen 10:19 says, "And the border of the Canaanites was from Sidon, as thou comest to Gerar, unto Gaza; as thou goest, unto Sodom, and Gomorrah, and Admah, and Zeboim, even unto Lasha."
Cush's sons were Seba, Havilah, Sabtah, Raamah, Sabtecha, and Nimrod
Nimrod's descendants are noted as cities, rather than children. He was responsible for Babel, Erech, Accad, Calneh (in the land of Shinar), and Resen (between Ninevaeh and Calah).
Mizraim (Nimrod's brother) son's were Ludim, Anamim, Lehabim, Naphtuhim, Pathrusim (father of the Philistim), and Caphtorim.
3) Shem was the youngest son. From his descendants would spring Israel, God's chosen people. I will insert details from Genesis 11 here, to amplify my understanding of the passage of time.
Shem was 100 when he begat Arphaxad. Since the flood kept his family on the ark roughly a year, and Noah was warned of the flood 100 years before it happened, Shem would have been three years old when his father started building. Shem lived to be 600.
Shem's sons were Elam, Asshur, Arphaxad, Lud, and Aram.
Aram's sons were Uz, Hul, Gether, and Mash.
Arphaxad's son was Salah. Arphaxad was 35 when he begat Selah. Arphaxad lived to be 438. His father Shem would have been 539, so he preceded his father Shem in death.
Salah's son was Eber. Salah was 30 when he begat Eber. Salah lived 433 years. Shem saw his son and grandson die before him.
Eber's sons were Peleg and Joktan. Eber was 34 when he begat Peleg. Eber died at 464. Peleg's name must have special meaning, as it is implied that the incident of Babel divided the tongues and nations during his lifetime.
Joktan's sons were Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab.
Peleg's (son of Eber) son was Reu. Peleg was 30 when he began Reu. Peleg lived to be 239.
Rue's son was Serug. He was 32 when he began Serug. Rue lived to be 239.
Serug's son was Nahor. He was 30 when he begat Nahor. Serug lived to be 230.
Nahor's son was Terah. He was 29 when he begat Terah. Nahor lived to be 148.
Terah's sons were Abram, Nahor (named after his father?), and Haran. Terah was 70 when he had his sons. There would have been at least two wives involved, as Abram married his half sister, Sarai.
Haran's son was Lot. Haran died before his father in the land of his nativity, Ur of the Chaldees. His daughter was Milcah. His son was Lot.
Nahor married his niece Milcah, who was Haran's daughter.
Together, Terah, Abram and Sarai, Nahor and Milcah, and Lot went from Ur of the Chaldees into the land of Haran. Terah lived to be 205.
Abram's sons were Ishmael(of Hagar) and Isaac (of Sarai). Abram was 86 when Ishmael was born. He was 100 when Isaac was born. After Sarai's death at 127, Abram married Keturah and she bore Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Abraham lived to be 175. Of course, the info on Abraham and Isaac is in later chapters, but by the time I got this far, my curiosity was killing me.
Isaac lived 180 years.
