Contradiction with 1 Chronicles 2:50-51
1 Chronicles 4:3 mentions "these were of the father of Etam" referring to descendants of Hur and Asher, whereas 1 Chronicles 2:50-51 lists descendants of Caleb who is also related to the lineage of Hur, creating confusion on his genealogy consistency.
1 Chronicles 2:50-51: These were the sons of Caleb the son of Hur, the firstborn of Ephratah; Shobal the father of Kirjathjearim, [Ephratah: also called, Ephreth]
Contradiction with 1 Chronicles 4:1
1 Chronicles 4:3 refers to Jezreel, Ishma, and Idbash as sons connected with the father of Etam, but 1 Chronicles 4:1 earlier lists only the descendants of Judah, suggesting a broader inclusion inconsistent with the specific lineage.
1 Chronicles 4:1: The sons of Judah; Pharez, Hezron, and Carmi, and Hur, and Shobal. [Carmi: also called, Chelubai or Caleb]
Contradiction with Numbers 26:20-21
The divisions of the tribe of Judah described in Numbers do not mention the names found in 1 Chronicles 4:3, which creates discrepancies in the lineage and accounting of family members.
Numbers 26:20-21: And the sons of Judah after their families were; of Shelah, the family of the Shelanites: of Pharez, the family of the Pharzites: of Zerah, the family of the Zarhites.
