Contradiction with Proverbs 20:12
Proverbs states that the hearing ear and the seeing eye are made by the Lord, implying that they should function properly, contrasting the idea in Mark 8:18 of having eyes and ears but not perceiving.
Proverbs 20:12: The hearing ear, and the seeing eye, the LORD hath made even both of them.
Contradiction with Isaiah 6:9-10
Isaiah emphasizes the people’s inability to understand God’s message due to a spiritual hardening, contrasting Mark 8:18 where having physical senses yet not understanding suggests a willful negligence.
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 13:16
Jesus states that His disciples are blessed because their eyes and ears do perceive, which is a direct contrast to the implication in Mark 8:18 of having seeing and hearing without comprehension.
Matthew 13:16: But blessed [are] your eyes, for they see: and your ears, for they hear.
Contradiction with Isaiah 35:5
This verse prophesies that the eyes of the blind shall be opened, and the ears of the deaf unstopped, suggesting a restoring of understanding, unlike the situation described in Mark 8:18.
Isaiah 35:5: Then the eyes of the blind shall be opened, and the ears of the deaf shall be unstopped.
Contradiction with Jeremiah 5:21
It describes people as foolish because they have eyes and see not, ears and hear not—an indictment of understanding rather than a physical lack, similar but more condemning compared to the implication in Mark 8:18.
Jeremiah 5:21: Hear now this, O foolish people, and without understanding; which have eyes, and see not; which have ears, and hear not: [understanding: Heb. heart]
