Jeremiah 43:6: [Even] men, and women, and children, and the king's daughters, and every person that Nebuzaradan the captain of the guard had left with Gedaliah the son of Ahikam the son of Shaphan, and Jeremiah the prophet, and Baruch the son of Neriah.

Contradiction with Jeremiah 41:16-18
These verses describe the fear and subsequent decision of Johanan and the people to flee to Egypt, which contrasts with Jeremiah choosing to stay in the land with Gedaliah in Jeremiah 40:6.
Jeremiah 41:16-18: Then took Johanan the son of Kareah, and all the captains of the forces that [were] with him, all the remnant of the people whom he had recovered from Ishmael the son of Nethaniah, from Mizpah, after [that] he had slain Gedaliah the son of Ahikam, [even] mighty men of war, and the women, and the children, and the eunuchs, whom he had brought again from Gibeon:
Contradiction with Jeremiah 42:10-11
God advises the remnant of Judah to stay in the land and not fear the king of Babylon, which aligns with Jeremiah's actions in 40:6, yet in practice, the people do not heed this advice and plan to flee, creating a contradiction between God's advice and the people's actions.
Jeremiah 42:10-11: If ye will still abide in this land, then will I build you, and not pull [you] down, and I will plant you, and not pluck [you] up: for I repent me of the evil that I have done unto you.
