Contradiction with Isaiah 6:9-10
These verses describe a situation where people intentionally do not understand or perceive, which contrasts with Isaiah 42:19's portrayal of the servant's blindness and deafness as unexpected or ironic.
Isaiah 6:9-10: And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not. [indeed, but understand: or, without ceasing, etc: Heb. in hearing, etc]
Contradiction with Matthew 13:13-15
Here, Jesus talks about speaking in parables so people will not see or hear, contradicting the idea of being blind or deaf without reason as in Isaiah 42:19.
Matthew 13:13-15: Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
Contradiction with John 9:39
Jesus mentions that He came for judgment so that the blind might see and those who see might become blind, which contrasts with the notion of unexpected blindness in Isaiah 42:19.
John 9:39: And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind.
Contradiction with 2 Corinthians 4:4
This verse speaks about the god of this world blinding unbelievers, which contradicts the servant's blindness being an inherent aspect in Isaiah 42:19.
2 Corinthians 4:4: In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
Contradiction with Romans 11:8
Paul mentions God giving a spirit of stupor, eyes that should not see, and ears that should not hear, echoing Isaiah 6:9-10, indicating a different kind of intentional blindness than in Isaiah 42:19.
Romans 11:8: (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear;) unto this day. [slumber: or, remorse]
Paradox #1
The contradiction or conflict could arise from the idea that the verse describes a servant or messenger who is "blind" or "deaf," which may seem inconsistent with the role of a servant or prophet who is expected to see and understand in order to faithfully execute God's will. This might raise questions about why a messenger would be chosen if they lack perception, or how they can effectively fulfill their mission.
