Contradiction with Psalm 90:10
It suggests that the days of our years are threescore years and ten, or even by reason of strength fourscore years, implying human life has a designated span rather than being crushed from morning to evening as Job 4:20 implies.
Psalm 90:10: The days of our years [are] threescore years and ten; and if by reason of strength [they be] fourscore years, yet [is] their strength labour and sorrow; for it is soon cut off, and we fly away. [The days...: Heb. As for the days of our years, in them are seventy years]
Contradiction with Ecclesiastes 3:1-2
It states that there is a time to be born and a time to die, suggesting that life and its end are part of a divine order, rather than arbitrary and sudden as implied in Job 4:20.
Ecclesiastes 3:1-2: To every [thing there is] a season, and a time to every purpose under the heaven:
Contradiction with Psalm 37:25
The verse expresses the observation that the righteous are not forsaken, contradicting the idea in Job 4:20 that men are destroyed without regard.
Psalm 37:25: I have been young, and [now] am old; yet have I not seen the righteous forsaken, nor his seed begging bread.
Contradiction with Psalm 121:7-8
These verses promise that the Lord shall preserve thee from all evil and keep thy life, which goes against the notion of being destroyed from morning to evening.
Psalm 121:7-8: The LORD shall preserve thee from all evil: he shall preserve thy soul.
Paradox #1
The contradiction in Job 4:20 could be seen as highlighting the fragility and insignificance of humans, which might seem inconsistent with the idea that humans are created in the image of God and valued by Him. This could create a conflict between the perception of human worth and the biblical assertion of human dignity.
