Contradiction with Ecclesiastes 7:20
Ecclesiastes says there is not a just man on earth who does good and does not sin, contradicting Job 36:4 which implies the speaker's knowledge is perfect because they are faultless.
Ecclesiastes 7:20: For [there is] not a just man upon earth, that doeth good, and sinneth not.
Contradiction with Romans 3:23
Romans states that all have sinned and fall short of the glory of God, which contradicts the implication in Job 36:4 that the speaker (possibly Elihu) might be perfect in knowledge.
Romans 3:23: For all have sinned, and come short of the glory of God;
Contradiction with 1 John 1:8
1 John asserts that if we claim to be without sin, we deceive ourselves, which contradicts Job 36:4's suggestion of possessing perfect knowledge implying sinlessness or perfection.
1 John 1:8: If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Paradox #1
The statement in Job 36:4 declares the speaker as perfect in knowledge. This can be seen as inconsistent because, from a theological standpoint, only God is considered to have perfect knowledge. Human claims to perfect knowledge can contradict the humility and limitations typically acknowledged in human understanding according to biblical teachings.
