"The
pure seed line of Seth ends with Noah. We
know this because the Lord mentions that everyone in
Seth’s seed line produces both sons and daughters.
After every descendent in the genealogy of
Seth it states this: “and begat sons and daughters”.
Only the sons are mentioned in Cain’s seed
line with the above exception of Naamah."
"It is most likely that if a Sethite
man married a Cainite woman, they could only have
sons, but if a Sethite woman married a Cainite man,
they could have both sons and daughters. We
know that Noah was the last of the pure seed line
because in the genealogy of Seth, Noah is the last
person mentioned and we see that Noah had three
sons, and no mention of daughters."
The pure seed line of Seth did not
end with Noah just because Noah had 3 sons
and no daughters. The so called pure seed
line which I have heard referred to as a righteous
line from which Jesus was born continued with
Noah's son Shem right on down through Nahor,
and these 9 men listed in the genealogy all had
sons and daughters if you read their genealogy in
Genesis 11:10-25. However, the Bible
tells us in Genesis 11:26 that Nahor's son Terah
had 3 sons who were named Abram, Nahor, and Haran,
but Terah had no daughters. So the pure
seed or righteous line doesn't depend on
whether a man has both sons
and daughters. In fact according to the
Bible, Adam had 3 sons with no mention of any
daughters either. So the pure seed or
righteous line did not stop with Adam, Noah
or with Terah, all of which had 3 sons and no
daughters. Then Terah's son Abram had 2 sons
(Ishmael and Isaac), and the Bible doesn't mention
Abram having daughters. Then Isaac has 2
sons (Esau and Jacob) and the Bible doesn't
mention Isaac having any daughters either.
So the genealogy of Jesus' mother Mary and
step-father Joseph can be traced all the way back
to Adam according to Luke 3:23-38 and to Abraham
in Matthew 1:1-17. Having sons and daughters
or not has nothing to do with being righteous or
evil.
In regard to the "giants' that you
mentioned in Numbers 33:13, please check the
chapter and verse because I think you are
referring to Numbers 13:33 which says, "And
there we saw the giants, the sons of Anak, [which
come] of the giants: and we were in our own sight
as grasshoppers, and so we were in their
sight." The first word "giants" in that
verse is Storng's Hebrew word #1368 while the
second word "giants" is word # 7497. Also
the word "giants" is last used in the book of
Joshua; there is no book called Josiah in the
Bible.
