Contradiction with 1 Kings 1:1-4
These verses describe King David as an old man who, despite his ailments, did not go out to face any foes, which contrasts with Benaiah's active and vigorous exploits for David as described in 1 Chronicles 11:22.
1 Kings 1:1-4: Now king David was old [and] stricken in years; and they covered him with clothes, but he gat no heat. [stricken...: Heb. entered into days]
Contradiction with 1 Chronicles 20:4-8
These verses describe other warriors' victories over giants, indicating the prowess of multiple heroes, not just Benaiah, which lessens his unique distinction in facing great foes as seen in 1 Chronicles 11:22.
1 Chronicles 20:4-8: And it came to pass after this, that there arose war at Gezer with the Philistines; at which time Sibbechai the Hushathite slew Sippai, [that was] of the children of the giant: and they were subdued. [arose: or, continued: Heb. stood] [Gezer: also called, Gob] [Sippai: also called, Saph] [the giant: or, Rapha]
Contradiction with 2 Samuel 23:20-23
This passage overlaps with 1 Chronicles 11:22 about Benaiah's same deeds, highlighting commendation but not necessarily contradiction, although it adds no extra grandeur to Benaiah’s feats over other warriors.
2 Samuel 23:20-23: And Benaiah the son of Jehoiada, the son of a valiant man, of Kabzeel, who had done many acts, he slew two lionlike men of Moab: he went down also and slew a lion in the midst of a pit in time of snow: [who...: Heb. great of acts] [lionlike...: Heb. lion of God]
Paradox #1
The potential scientific inconsistency might stem from the described event involving extreme weather conditions. The actions described could seem improbable from a scientific perspective due to physical limitations of humans in such conditions. However, without specific details, any claimed inconsistency remains speculative.
Paradox #2
The contradiction or conflict might arise from the glorification of violence or killing, as the actions in the verse are celebrated and seen as heroic. In some moral or ethical frameworks, taking a life is viewed negatively, so this celebration of violence could seem inconsistent with those views.
