Contradiction with Proverbs 12:19
While 2 Samuel 14:18 suggests speaking the truth, Proverbs 12:19 states that truthful lips endure forever, implying truth is not temporary or situational.
Proverbs 12:19: The lip of truth shall be established for ever: but a lying tongue [is] but for a moment.
Contradiction with James 3:17
This verse highlights wisdom from above is pure and honest, suggesting any request to speak falsely contradicts the nature of divine wisdom if interpreted from 2 Samuel 14:18 as involving deception.
James 3:17: But the wisdom that is from above is first pure, then peaceable, gentle, [and] easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. [partiality: or, wrangling]
Contradiction with Ephesians 4:25
Ephesians urges believers to put away falsehood and speak truthfully, possibly contradicting the request in 2 Samuel 14:18 if such a request involved any untruth.
Ephesians 4:25: Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another.
