Contradiction with 2 Samuel 23:8
This verse describes Josheb-Basshebeth as the chief of the captains, whereas 1 Chronicles 12:4 includes a different list of principal men, causing potential inconsistency in recognizing notable leaders.
2 Samuel 23:8: These [be] the names of the mighty men whom David had: The Tachmonite that sat in the seat, chief among the captains; the same [was] Adino the Eznite: [he lift up his spear] against eight hundred, whom he slew at one time. [The Tachmonite...: or, Joshebbassebet the Tachmonite, head of the three] [whom he...: Heb. slain] [he lift...: from (1ch:) whom he...: Heb. slain]
Contradiction with 1 Chronicles 11:11
This verse mentions Jashobeam as the chief of David's mighty men, but 1 Chronicles 12:4 lists another set of leaders without highlighting Jashobeam, which may create a sense of contradiction in their leadership roles.
1 Chronicles 11:11: And this [is] the number of the mighty men whom David had; Jashobeam, an Hachmonite, the chief of the captains: he lifted up his spear against three hundred slain [by him] at one time. [an Hachmonite: or, son of Hachmoni]
Contradiction with Judges 7:3
This verse focuses on Gideon's reduction of his troops, which contrasts with the addition of warriors to David's ranks mentioned in 1 Chronicles 12:4, reflecting differing approaches to building an army.
Judges 7:3: Now therefore go to, proclaim in the ears of the people, saying, Whosoever [is] fearful and afraid, let him return and depart early from mount Gilead. And there returned of the people twenty and two thousand; and there remained ten thousand.
