#1 EX. 20:3 ("You shall not have no other gods before me"--KJ, RS, ML, AS, NAS, MT, NI) versus ("You shall have no other gods except or besides me"--JB, NAB, TEV, BBE, LV). A clash over the first commandment arises from the fact that the former group merely says you must put the god of the Bible at the top of the list. Worship of other gods is not prohibited.
#2 1 SAM. 6:19 ("But God smote of the men of Beth-shemesh...50,070.... "--KJ, AS, NWT, NAS, MT)
versus ("the Lord smote 5,070 men of the people"--LV).
versus ("...he slew 70 men of them"--RS, LB, JB, BBE, NEB, NAB, TEV, NI)
Whether God killed 70 people or over 50,000 for a relatively innocuous act bears directly on the biblical teaching in Deut. 32:4, Psalm 9:8, etc. that God is just and righteous. Apparently this troubles scholars and accounts for the dramatic reduction in numbers in many recent translations.
#3 JOB 19:26 ("...yet in my flesh shall I see God"--KJ, LB, NI, TEV, NWT) versus ("then from or without my flesh I shall see God"--RS, ML, JB, AS, BBE, NAB, MT, NAS). The latter denies the physical resurrection of mankind which the former affirms.
#4 PROV. 14:33 ("...but it <wisdom> is not known in the heart of the fools"--RS, NAB, JB, BBE, TEV, LV) versus ("But in the inward part of fools it maketh itself known"). Biblical teaching is contradictory as to whether wisdom lies within fools, although one might argue the inward part does not mean the heart.
#5 PROV. 28:3 ("A ruler who oppresses the poor is like a driving rain...."--NI, BBE, NAB, TEV) versus "A poor man that oppresseth the poor"--KJ, RS, ML, LB, AS, NAS, MT, LV). It's hard to visualize how a poor man could oppress the poor which is probably why the NI, NAB and TEV translators reversed the script. The biblical view of an important social issue is quite muddled.
#6 ISA. 7:14 ("Behold, a virgin shall conceive, and bear a son...."--KJ, ML, LB, NI, AS, NAB, NAS, LV) versus ("Behold, a young woman shall conceive and bear a son...."--RS, BBE, NEB, TEV, MT) or (a young maiden--JB, NWT). This clash has been debated for centuries and goes to the heart of a critical biblical teaching because it's the only OT prophecy referring to the Messiah's virgin birth.
#7 DAN. 9:24 ("...and to anoint the most holy"--KJ, AS, NI) versus ("...and to anoint a most holy place"--RS, LB, BBE, NEB, TEV, NAS, MT). The 9th chapter of Daniel has one of the most important of all OT prophecies and it's rather difficult to see how it could be referring to Jesus, i.e. be messianic, when conflict exists as to whether the most holy is a man or a place.
#8 MICAH 5:2 ("...whose goings forth have been from old from everlasting"--KJ, ML, LB, AS, BBE, NWT, NAS, LV) versus ("...whose origin is from old from ancient days"--RS, JB, NI, NEB, TEV, MT, NAB). Micah 5:2 is supposedly one of the most precise OT prophecies because it supposedly predicts the Messiah would be born in Bethlehem. But how could it be referring to Jesus if his goings were "from ancient days" which, unlike "everlasting" denotes a beginning at some time in the distant past? Whether or not the Messiah had an origin is crucial.
#9 MATT. 12:40 ("For as Jonas was 3 days and 3 nights in the whale's belly"--KJ, RS, AS, NAB, LV) versus ("For as Jonas was 3 days and 3 nights in the belly of the sea-monster"--ML, JB, NEB, NAB) versus ("For as Jonas was in the great fish 3 days and 3 nights"--NI, NWT, TEV, LB, BBE). This conflict bears directly on the accuracy of comments by Jesus since whales are not fish and vice versa.
#10 MARK 1:1 ("The beginning of the gospel about Jesus Christ"--NI, LB, JB, TEV, NWT) versus ("The beginning of the gospel of Jesus Christ"--KJ, RS, ML, AS, BBE, NEB, NAB, NAS, LV). The former does not say Jesus wrote the Book of Mark while the latter all but says he did.
