Contradiction with Genesis 1:31
This verse states that God saw everything He made and it was very good, contradicting the plague of frogs being disruptive and a nuisance in Exodus 8:14.
Genesis 1:31: And God saw every thing that he had made, and, behold, [it was] very good. And the evening and the morning were the sixth day. [And the evening...: Heb. And the evening was, and the morning was etc.]
Contradiction with Leviticus 26:6
Here, God promises peace in the land and safety from harmful creatures, contradicting the chaos and infestation caused by the frogs in Exodus 8:14.
Leviticus 26:6: And I will give peace in the land, and ye shall lie down, and none shall make [you] afraid: and I will rid evil beasts out of the land, neither shall the sword go through your land. [rid: Heb. cause to cease]
Contradiction with Isaiah 45:7
God claims responsibility for creating peace and evil, which implies all is under His control, conflicting with the unintended consequences of the frogs in Exodus 8:14.
Isaiah 45:7: I form the light, and create darkness: I make peace, and create evil: I the LORD do all these [things].
Contradiction with Romans 8:28
This verse indicates that all things work for good for those who love God, which seems to contradict the troubling situation in Exodus 8:14 where the plague is distressing.
Romans 8:28: And we know that all things work together for good to them that love God, to them who are the called according to [his] purpose.
