How one can believe the Bible is wrong and still be an inerrantist

Do you recall this post: The Height of Goliath

“The Bible records the famous strife between David and the giant Goliath, ending with the defeat of the latter. Goliath was "six cubits and a span" in height--over nine feet tall (1 Samuel 17:4). However, an earlier translation of this tale found in the Dead Sea Scrolls puts Goliath at just under two meters tall, rather than three meters as had been written in later versions. This greatly increases the validity of claims that Goliath may have been a real person, being gigantic in stature compared to the average height of a man in the early classical era of around 1.6 meters compared to around 1.75 today.”

Allow me to create a scenario.

A Christian OT professor reads the story of David and Goliath and comes to the conclusion that the story is too ridiculous to be true. The professor confesses that he does not believe that Goliath was 9 feet tall as the Bible records. He thus states that the Bible is wrong. This person has now just refuted a belief in the inerrancy of the Scripture.

Now a second Christian OT professor reads the story of David and Goliath and comes to the conclusion that the story is too ridiculous to be true. The professor decides to reevaluate the Masoretic text of the Hebrew Bible (circa 800 CE), the Septuagint Greek text of the OT (circa 200 BCE) and the Dead Sea Scrolls (circa 200 BCE). Having read the DSC version of the OT, he comes to conclusion that the Masoretic text (from which our OT is derived) has a textual error in it. The original text of the book of Samuel had the correct and inerrant height of Goliath as 2 cubits, but some scribal error led subsequent texts to record his height as 3 cubits. He thus states that while the Masoretic text is wrong, the original text of the Bible (which we do not have) was correct. This person has now just refuted the text of our OT manuscripts but sustained his belief in the inerrancy of the Scripture.

Now while both Christian OT professors reject the idea that Goliath was 3 cubits high and refute the Masoretic text of the Bible, only the second professor would be able to teach in an SBC seminary.
