Contradiction with Jeremiah 39:4
This verse suggests that the city was taken and the men of war fled before the walls were breached, which contrasts with Jeremiah 52:7 that describes them fleeing after a breach was made.
Jeremiah 39:4: And it came to pass, [that] when Zedekiah the king of Judah saw them, and all the men of war, then they fled, and went forth out of the city by night, by the way of the king's garden, by the gate betwixt the two walls: and he went out the way of the plain.
Contradiction with 2 Kings 25:4
Similar to Jeremiah 52:7, but states they fled by night by the way of the gate between two walls, which presents a discrepancy with details of their escape route.
2 Kings 25:4: And the city was broken up, and all the men of war [fled] by night by the way of the gate between two walls, which [is] by the king's garden: (now the Chaldees [were] against the city round about:) and [the king] went the way toward the plain.
Contradiction with Ezekiel 33:21
Mentions the city being smitten, which contradicts the precise timing of events in Jeremiah 52:7.
Ezekiel 33:21: And it came to pass in the twelfth year of our captivity, in the tenth [month], in the fifth [day] of the month, [that] one that had escaped out of Jerusalem came unto me, saying, The city is smitten.
Contradiction with 2 Chronicles 36:17-19
Indicates the Chaldeans broke into the city and describes the destruction differently, thus contrasting with the emphasis on the escape of the city leaders in Jeremiah 52:7.
2 Chronicles 36:17-19: Therefore he brought upon them the king of the Chaldees, who slew their young men with the sword in the house of their sanctuary, and had no compassion upon young man or maiden, old man, or him that stooped for age: he gave [them] all into his hand.
