Contradiction with Numbers 23:19
This verse states that God does not change His mind or lie, contrasting with the implication of negotiation or change seen in Exodus 8:5 where God responds to Moses' request to change a situation with the frogs.
Numbers 23:19: God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?
Contradiction with James 1:17
This verse talks about God as constant and unchanging, whereas in Exodus 8:5, God responds to Moses' intercession by altering the situation.
James 1:17: Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
Contradiction with Malachi 3:6
God is described as unchanging in this verse, which appears to contradict the dynamic interaction and response in Exodus 8:5.
Malachi 3:6: For I [am] the LORD, I change not; therefore ye sons of Jacob are not consumed.
Contradiction with Isaiah 55:8-9
These verses highlight God's thoughts and ways as higher than humans', contrasting with the human-like negotiation in Exodus 8:5.
Isaiah 55:8-9: For my thoughts [are] not your thoughts, neither [are] your ways my ways, saith the LORD.
