Contradiction with 1 Chronicles 12:19
This verse contradicts 1 Samuel 27:7 by indicating that David's alliance with the Philistines was questioned, whereas 1 Samuel 27:7 suggests he lived among them without incident.
1 Chronicles 12:19: And there fell [some] of Manasseh to David, when he came with the Philistines against Saul to battle: but they helped them not: for the lords of the Philistines upon advisement sent him away, saying, He will fall to his master Saul to [the jeopardy of] our heads. [to the...: Heb. on our heads]
Paradox #1
1 Samuel 27:7 might have a contradiction with the timeline of events described in other parts of the Bible, such as how long David stayed among the Philistines compared to how it's described in other chapters. There could be inconsistencies in the exact duration or timing when cross-referenced with other verses.
