Contradiction with Isaiah 1:18
Jeremiah 18:13 questions if a nation has done such a thing as forsaking God, implying it's unheard of, while Isaiah 1:18 shows God inviting sinful people to reason together and find forgiveness, suggesting human disobedience is common.
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 Ezekiel 16:32
Jeremiah 18:13 marvels at Israel's forsaking of God, yet Ezekiel 16:32 likens Israel to an adulterous wife, showing unfaithfulness as a recurring theme.
Ezekiel 16:32: [But as] a wife that committeth adultery, [which] taketh strangers instead of her husband!
Contradiction with Hosea 4:1
While Jeremiah 18:13 calls Israel's actions unheard of, Hosea 4:1 speaks of a lack of truth and faithfulness in Israel, indicating continuous transgression.
Hosea 4:1: Hear the word of the LORD, ye children of Israel: for the LORD hath a controversy with the inhabitants of the land, because [there is] no truth, nor mercy, nor knowledge of God in the land.
