4 they are conceited and understand nothing. They have an unhealthy interest in controversies and quarrels about words that result in envy, strife, malicious talk, evil suspicions
4 he is puffed up with conceit and understands nothing. He has an unhealthy craving for controversy and for quarrels about words, which produce envy, dissension, slander, evil suspicions,
4 tag them for what they are: ignorant windbags who infect the air with germs of envy, controversy, bad-mouthing, suspicious rumors.
4 he is proud, knowing nothing, but is obsessed with disputes and arguments over words, from which come envy, strife, reviling, evil suspicions,
4 Anyone who teaches something different is arrogant and lacks understanding. Such a person has an unhealthy desire to quibble over the meaning of words. This stirs up arguments ending in jealousy, division, slander, and evil suspicions.
Matthew Henry's Commentary on 1 Timothy 6:4
Commentary on 1 Timothy 6:1-5
(Read 1 Timothy 6:1-5)
Christians were not to suppose that religious knowledge, or Christian privileges, gave them any right to despise heathen masters, or to disobey lawful commands, or to expose their faults to others. And such as enjoyed the privilege of living with believing masters, were not to withhold due respect and reverence, because they were equal in respect to religious privileges, but were to serve with double diligence and cheerfulness, because of their faith in Christ, and as partakers of his free salvation. We are not to consent to any words as wholesome, except the words of our Lord Jesus Christ; to these we must give unfeigned consent. Commonly those are most proud who know least; for they do not know themselves. Hence come envy, strife, railings, evil-surmisings, disputes that are all subtlety, and of no solidity, between men of corrupt and carnal minds, ignorant of the truth and its sanctifying power, and seeking their worldly advantage.
