Contradiction with Proverbs 12:25
This verse speaks of anxiety in the heart causing depression, contrasting with Job 4:4 where words are depicted as uplifting and strengthening the weak.
Proverbs 12:25: Heaviness in the heart of man maketh it stoop: but a good word maketh it glad.
Contradiction with 1 Thessalonians 5:14
Urges to comfort the fainthearted and uphold the weak, while Job 4:4 suggests strength from words, there's no promise of support or comfort, unlike the directive in this verse.
1 Thessalonians 5:14: Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all [men]. [exhort: or, beseech] [unruly: or, disorderly]
Contradiction with James 3:10
From the same mouth proceed blessing and cursing, highlighting the dual nature of words, whereas Job 4:4 implies only a positive influence.
James 3:10: Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.
Contradiction with James 1:26
If anyone thinks he is religious but does not bridle his tongue, his religion is useless, opposing Job 4:4 which assumes beneficial use of speech.
James 1:26: If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion [is] vain.
