My question is at the very bottom of this; I'm using the KJV.
According to the following 4 verses, Shem's son Arphaxad would have been born on the ark.
Gen 5:32 And Noah was 500 years old: and Noah begat Shem, Ham, and Japheth.
Gen 7:11 In the 600th year of Noah's life, in the 2nd month, the 17th day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
[If Noah was 600 years old here Shem was about 100 years old (600 – 500)].
Gen 11:10 Shem was an 100 years old, and begat Arphaxad
Gen 8:13 And it came to pass in the 601st year (of Noah’s life), in the 1st month, the 1st day of the month, the waters were dried up from off the earth: and Noah removed the covering of the ark, and looked, and, behold, the face of the ground was dry.
(If Noah was 601 years old here with Shem 500 years younger, Shem would have been 101 and Arphaxad at least born).
However, accordingly to the citings below, no children left the ark.
Gen 8:15-19 And God spake unto Noah, saying, Go forth of the ark, thou, and thy wife, and thy sons, and thy sons' wives with thee. Bring forth with thee every living thing that is with thee, of all flesh, both of fowl, and of cattle, and of every creeping thing that creepeth upon the earth; that they may breed abundantly in the earth, and be fruitful, and multiply upon the earth. And Noah went forth, and his sons, and his wife, and his sons' wives with him: Every beast, every creeping thing, and every fowl, and whatsoever creepeth upon the earth, after their kinds, went forth out of the ark.
Gen 9:18-19 And the sons of Noah, that went forth of the ark, were Shem, and Ham, and Japheth: and Ham is the father of Canaan. These are the three sons of Noah: and of them was the whole earth overspread.
At first it seems Arphaxad would have been born on the ark. While Noah brought with him every living thing, Arphaxad isn't shown as one. Next, God doesn't address or include Arphaxad as one who would be peopling the earth. However, “And Arphaxad lived 530 years, and begat Salah:" (Gen 11:12) (KJV).
How can this be reconciled?
