Morey attacks the LXX in chapter 3 of his book. Feel free to edit whereever you see fit.
I didn't touch everything he mentioned but I responded to a huge chunk of it.http://ancientchristiandefender.blogspot.com/2008/03/why-lxx-shouldnt-be-judged-by-mt.html
Why the LXX shouldn't be judged by the MT
When some reformed protestants say the LXX is corrupt. What they mean is it differs from the MT. The MT is not the original hebrew text type. Infact, there are several different Hebrew text types. The LXX follows a different Hebrew text type and besides, the MT was butchered(edited) in certain parts by nonbelieving jews for theological reasons.
The LXX shouldn't be judged by the MT, because the MT is a post Christian Hebrew text that has been edited and compiled from about 150 A.D. to about 900A.D.
The LXX is a 3rd or 2nd century B.C. Greek Translation of an earlier Hebrew text. And when the dead sea scrolls were found. The LXX cynics were surprized to find out that where the Dead Sea scrolls differed substantialy from the MT it usually agreed with the LXX. Now the LXX and the MT agree in most places, but in some parts they do differ. What we have today is called by scholars the "Hexaplar recension". It is called that because it is a combined text of the hebrew of Origens day along with 5 or 6 greek translations. 3 of which were post christian literal greek translations by nonbelieving Jews that rejected christianity. The LXX had it's own colomn in the Hexaplar. Thus the Hexaplar was what we would call in modern times a Parallel Bible. A couple other recension texts were also around as spoken of by Jerome.
Tertullian speaks about the Hebrew text type that the LXX was based on, which was still in existence in his day."That the understanding of their books might not be lacking, this also the
Jews supplied to ptolemy. For they gave him seventy-two interpreters......The
same account is given by Aristeas. So the King left these works unlocked to all,
in the Greek language. To this day, at the temple of serapis, the libraries of
Ptolemy are to be seen, with the identical Hebrew originals in them. The Jews,
too, read them publicly."

The Post Nicene christian Saint Athanasius also embraced some of the deuterocanonical books in his 3 class system of books. His 3 tier system of Canonical scripture(which included the books of Baruch, and the letter of Jeremiah)
, the scripture that is read(the rest of the deutero books)
, and the uninspired Apocrypha(other books like the Apocalypse of Peter, the Apocalypse of Abraham, the book of Noah, the apocalypse of Adam, Acts of Peter, Ascension of Isaiah.....ect)

Also I would like to note that the dead sea scrolls had the books of Tobias, Sirach, Baruch, and psalm 151 of David.
The LXX and the dead sea "4QSam-a"
are very similar.
How tall was Goliath?
1 Samuel 17:4 of the dead sea scroll "4QSam-a"
says "4 cubits and one span"
. The LXX says:
1st Kingdoms 17:4(1st Samuel 17:4) "And a mighty man went out from the
battle line of the Philistines named Goliath, from Gath. His height was four
cubits and a span."
The MT says
1st Samuel 17:4 "And there went out a champion out of the camp of the
Philistines, named Goliath, of Gath, whose height was six cubits and a
Recent Archeology of the middle eastern region in regards to the ancient tales of giants in that area agrees with the dead sea scrolls and LXX of 4 cubits and a span.4QGen-k
fragment has the longer reading of "and dry land appeared"
in its text.
The LXX says
Gen 1:9 "Then God said, let the water under heaven be gathered together
into one place, and let the dry land appear"; and it was so. The water under
heaven was gathered into its places, and the dry land appeared."
The MT says"9And God said, Let the waters under the heaven be gathered together unto one
place, and let the dry land appear: and it was so."
This shows the Hebrew that the LXX was based on was very similar to the one of the dead sea scrolls. At least in regards to Genesis.4Q Exod-a
of the DSS says of Exodus 1:5 "75 souls"
The lxx says:
"All those who were the seed of Jacob were seventy-five persons (for
Joseph was in Egypt already)."
The MT says:
"And all the souls that came out of the loins of Jacob were seventy souls:
for Joseph was in Egypt already."
The Dead sea scroll fragment agreed with the LXX. Also the New Testament agrees with the LXX.
Acts chapter 7:14 says:
"Then Joseph sent and called his father Jacob and all his relatives to him, seventy-five people."
Steven quoted the LXX, yet some people would like to re-write history and pretent that Jesus and the Apostles didn't make use of the LXX. Also some people would like to pretent that the LXX only had the first five books of Moses. The fact that the New Testament quotes the LXX in other places shows that the LXX had more books in it than just the first 5 books of Moses.
4QDeut-j in Deuteronomy 32:8 agrees with the LXX in that it has "according to the number of the sons of God"
"When the Most High divided the nations, when He scattered the Sons of
Adam, He set the boundaries of the nations by the number of God's angels"
The MT says
"When the Most High divided to the nations their inheritance, when he
separated the sons of Adam, he set the bounds of the people according to the
number of the children of Israel."
The 5/6HevPs of Psalm 22:17 says "They have pierced my hands and feet"
The LXX says:
Psalms 21:17(22:17 in MT) "For many dogs surrounded me; an assembly of evildoers
enclosed me; they pierced my hands and my feet."
The MT says:
"I may tell all my bones: they look and stare upon me."The New Testament in comparision with the LXX and MT

What did Jesus read in Luke 4:18-19?
NKJV Luke 4:16-21""So He came to Nazareth, where He had been brought up. And as His custom
was, He went into the synagogue on the Sabbath day, and stood up to read. And He
was handed the book of the prophet Isaiah. And when He had opened the book, He
found the place where it was written:
“ The Spirit of the LORD is upon Me,
Because He has anointed Me To preach the
gospel to the poor; He has sent Me to heal
the brokenhearted, To proclaim liberty to the
captives And recovery of sight to the
blind, To set at liberty those who are
oppressed; To proclaim the acceptable
year of the LORD.”
Then He closed the book, and gave it back to the attendant and
sat down. And the eyes of all who were in the synagogue were fixed on Him. And
He began to say to them, “Today this Scripture is fulfilled in your
The LXX says:
Brentons lxx Isaiah 61:1-2"The Spirit of the Lord is upon me, because he has anointed me; he has sent
me to preach glad tidings to the poor, to heal the broken in heart, to proclaim
liberty to the captives, and recovery of sight to the blind; to declare
the acceptable year of the Lord, and the day of recompence; to comfort all that
The MT says
KJV Isaiah 61:1-2""The Spirit of the Lord GOD is upon me; because the LORD hath anointed me
to preach good tidings unto the meek; he hath sent me to bind up the
brokenhearted, to proclaim liberty to the captives, and the opening of the
prison to them that are bound;
To proclaim the acceptable year of
the LORD, and the day of vengeance of our God; to comfort all that
You can't really see it in english but Jesus followed the greek of the LXX.
Matthew 1:22-23 says:
NKJV"So all this was done that it might be fulfilled which was spoken by the
Lord through the prophet, saying: “Behold, the virgin shall be with child, and
bear a Son, and they shall call His name Immanuel,” which is translated, “God
Brentons LXX says:
Esaias 7:14"Therefore the Lord himself shall give you a sign; behold, a virgin shall
conceive in the womb, and shall bring forth a son, and thou shalt call his name
The MT says
Well. I wasn't able to find a translation that went with the MT. Instead, they all chose to go with the LXX. But the MT says young woman......not virgen. However, there is evidence that the Jews who used the dead sea scrolls did understand that hebrew word in a similar way that the Jewish translaters of the LXX did. So it could have been a common interpretation before the time of Christ as well as during the time of Christ. The MT was edited for hundreds of years after 150 A.D. It is well known that the Jewish nonbelievers edited alot of the Messianic prophecies because of the rise of Christianity, and conversion of their own peoples.
Romans 9:17 says
NKJV"For the Scripture says to the Pharaoh, “For this very purpose I have raised you up, that I may show My power in you, and that My name may be declared in all the earth.”"
The LXX of Exodus 9:16 says:
Brentons lxx"And for this purpose hast thou been preserved, that I might display in thee my strength, and that my name might be published in all the earth."
The NASB says of Exodus 9:16"But, indeed, for this reason I have allowed you to remain, in order to show you My power and in order to proclaim My name through all the earth."
Romans 9:26 NKJV“And it shall come to pass in the place where it was said to them, ‘ You are not My people,’ There they shall be called sons of the living God.”
Hosea 1:10"Yet the Number of the children of Israel shall be as the sand of the sea, which shall not be measured or numbered. Then it shall come to pass in the place where it was said to them, 'You are not my people,' Even then they shall be called the sons of the living God."
The MT says
KJV"Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured nor numbered; and it shall come to pass, that in the place where it was said unto them, Ye are not my people, there it shall be said unto them, Ye are the sons of the living God."
You can't see it in english but Paul was following the LXX in Romans 9:25-26. The same is true for Romans 9:27; 9:29; and 9:33.
It is well known that the LXX was the Christian Old Testament. Yes you had a few christians from time to time that had their own personal view against the LXX, but over all when pushed came to shove and when big councils gathered. The LXX stayed with the Church. To Judge the LXX with the eyes of the MT is to judge the Old Testament that Christians used for 2,000 years.
