2 Samuel 23:8 and 1 Chronicles 11:11 are put against each other because 2 Samuel says that Jashobeam, David's chief captain killed 800 men with his spear at one time but 1 Chronicles says he killed 300 men. The Skeptic's Annotated Bible does not think that Christians have responded to this. They should have looked harder. Jay Smith and others wrote a website that answers 101 Contradictions in the Bible Muslims bring up. On their site they point out:
It is quite possible that both authors may have described two different incidents, though by the same man, or one author may have only mentioned in part what the other author mentions in full.
Concluding that there is a contradiction or one of the authors is wrong there is unwarranted. Neither author says that they are talking about the same event although they are talking about the same man.
How many men did the chief of David's captains kill?
