My question is at the very bottom of this.
According to the following 4 verses, Shem's son Arpachshad would have been born on the ark.
Gn 5:32 When Noah was 500 years old, he became the father of Shem…
Gn 7:11 In the 600th year of Noah’s life, in the 2nd month, on the 17th day of the month...the floodgates of the sky were opened. (If Noah was 600 years old here Shem was about 100 years old).
Gn 11:10 When Shem was 100 years old, he became the father of Arpachshad…
Gn 8:13 In the 601st year of Noah's life, in the 1st month, on the 1st day of the month, the water began to dry up on the earth. ...In the 2nd month (of the 601st year of Noah's life), on the 27th day, the earth was dry. (If Noah was 601 at this point, Shem would have been 101, and Arpachshad at least born).
However, accordingly to the citings below, it doesn't seem any male children got off, or were brought off, the ark.
Gn 8:15-17 Then God said to Noah "Go out of the ark, together with your wife and your sons and your sons' wives. Bring out with you every living thing that is with you-all bodily creatures-be they birds or animals or creeping things of the earth-and let them abound on the earth, breeding and multiplying on it".
Gn 8:18-19 ...Noah came out (of the ark), together with his wife and his sons and his sons' wives; and all the animals, wild and tame, all the birds, and all the creeping creatures of the earth left the ark, one kind after another.
Gn 9:18-19 The sons of Noah who came out of the ark were Shem, Ham and Japheth. (Ham was the father of Canaan). These three were the sons of Noah, and from them the whole earth would be peopled.
At first it seems Arpachshad would have been born on the ark. While Noah brought with him every living thing, Arpachshad isn't shown as one. Next, God doesn't address or include Arpachshad as one who would be peopling the earth. However, "When Arpachshad was 35 he became the father of Shelah" (Gn 11:12).
How can this be reconciled on its own?
