Contradiction with Deuteronomy 32:39
Deuteronomy 32:37 asks about the gods in whom people trusted, suggesting they are unable to save, while 32:39 declares that only God is able to kill and make alive.
Deuteronomy 32:39: See now that I, [even] I, [am] he, and [there is] no god with me: I kill, and I make alive; I wound, and I heal: neither [is there any] that can deliver out of my hand.
Contradiction with Isaiah 43:11
Isaiah 43:11 states that apart from God, there is no savior, which contrasts with the rhetorical question in Deuteronomy 32:37 about false gods that cannot save.
Isaiah 43:11: I, [even] I, [am] the LORD; and beside me [there is] no saviour.
Contradiction with Psalm 115:4-7
Psalm 115 describes idols as having mouths but not speaking, which contrasts with the implication in Deuteronomy 32:37 that the effectiveness and power of false gods are questioned.
Psalm 115:4-7: Their idols [are] silver and gold, the work of men's hands.
