Contradiction with Romans 11:32
This verse speaks of God's mercy on all, which contradicts the idea of divine judgment and forcing Pharaoh’s hand as seen in Exodus 9:1.
Romans 11:32: For God hath concluded them all in unbelief, that he might have mercy upon all. [concluded...: or, shut them all up together]
Contradiction with Isaiah 1:18
This verse invites reasoning together for forgiveness, which contradicts the directive command and impending judgment in Exodus 9:1.
Isaiah 1:18: Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
Contradiction with Matthew 5:44
This verse instructs to love enemies and do good to them, which contradicts the act of punishment and plagues in Exodus 9:1.
Matthew 5:44: But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
Contradiction with 2 Peter 3:9
This verse indicates God is patient, not wanting anyone to perish, contrasting with the immediate directive and consequence threatened in Exodus 9:1.
2 Peter 3:9: The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
Contradiction with Jonah 4:2
Jonah describes God as gracious and merciful, slow to anger, which seems in opposition to the swift command given in Exodus 9:1.
Jonah 4:2: And he prayed unto the LORD, and said, I pray thee, O LORD, [was] not this my saying, when I was yet in my country? Therefore I fled before unto Tarshish: for I knew that thou [art] a gracious God, and merciful, slow to anger, and of great kindness, and repentest thee of the evil.
Paradox #1
Exodus 9:1 instructs Pharaoh to let the Israelites go, but critics might argue that it's inconsistent with the notion of free will. God hardens Pharaoh's heart, affecting his ability to choose freely, which some see as a contradiction.
