Contradiction with Ezekiel 13:6
Ezekiel 13:6 condemns false prophets who claim false visions and divinations not from God, which contrasts with the accusation in Jeremiah 43:3 that Baruch is misleading Jeremiah for personal reasons.

Numbers 23:19 claims God is not a man that He should lie, which contradicts the implication in Jeremiah 43:3 that prophetic messages could be influenced by human schemes like those attributed to Baruch.

Contradiction with Deuteronomy 18:20
Deuteronomy 18:20 decrees death for a prophet who speaks presumptuously, suggesting a severe consequence that doesn’t align with the idea of Jeremiah being deceitfully influenced by Baruch as stated in Jeremiah 43:3.
Deuteronomy 18:20: But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.
