Contradiction with 1 Corinthians 14:22
Isaiah 28:11 suggests that speaking with other tongues is a sign to unbelievers, whereas 1 Corinthians 14:22 notes that tongues are a sign not to believers but to unbelievers.
1 Corinthians 14:22: Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying [serveth] not for them that believe not, but for them which believe.
Contradiction with 1 Corinthians 14:23
Isaiah 28:11 implies that tongues can be a meaningful message, but 1 Corinthians 14:23 suggests that speaking in tongues may cause confusion and make people think believers are mad without interpretation.
1 Corinthians 14:23: If therefore the whole church be come together into one place, and all speak with tongues, and there come in [those that are] unlearned, or unbelievers, will they not say that ye are mad?
Contradiction with Acts 2:4-6
Isaiah 28:11 implies languages used will be incomprehensible to those who hear them as a sign, while Acts 2:4-6 describes tongues that were comprehensible to every listener in their own language.
Acts 2:4-6: And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
Contradiction with Genesis 11:7
Isaiah 28:11 alludes to a purposeful act of sending a clear, albeit foreign, message, while Genesis 11:7 discusses confusing language leading to misunderstanding as a divine act.
Genesis 11:7: Go to, let us go down, and there confound their language, that they may not understand one another's speech.
Paradox #1
The potential contradiction in Isaiah 28:11 could be related to the issue of communication and understanding. The verse talks about people being spoken to in a language they don’t understand, which might seem unfair or confusing. This raises questions about the effectiveness and fairness of delivering a message in a way that people cannot grasp, potentially conflicting with ideas of clear communication and justice.
