Contradiction with Isaiah 6:9
While Ezekiel 3:5 suggests being sent to a people with a similar language makes communication easier, Isaiah 6:9 emphasizes that the people will hear but not understand, regardless of language.
Isaiah 6:9: 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 13:14-15
Contradicts Ezekiel 3:5 by showing that understanding is not guaranteed even when the message is delivered in the same language; people may still be spiritually blind or deaf.
Matthew 13:14-15: And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:
Contradiction with Acts 28:26-27
Similar to Matthew 13:14-15, this passage highlights that communication in the same language does not necessarily lead to understanding because of hardened hearts, contrary to the implication in Ezekiel 3:5.
Acts 28:26-27: Saying, Go unto this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see, and not perceive:
Contradiction with Hebrews 5:11
Suggests that it's the maturity of the listener, not merely language, that enables understanding, whereas Ezekiel 3:5 implies language is a key barrier.
Hebrews 5:11: Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.
