Contradiction with Isaiah 45:7
This verse describes God as creating evil, which appears to contradict the constant praise and goodness attributed to God in Psalms 106:1.
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 Exodus 32:14
God repenting of the evil he thought to do unto his people suggests a changeability not consistent with the unwavering goodness in Psalms 106:1.
Exodus 32:14: And the LORD repented of the evil which he thought to do unto his people.
Contradiction with Lamentations 3:38

Lamentations 3:38: Out of the mouth of the most High proceedeth not evil and good?
