Contradiction with 2 Kings 24:18
This verse gives a different account of Zedekiah’s age (21 years old) and reign duration (11 years), matching Jeremiah 52:1 but seemingly contradicting the implications around the events of his rule in other scriptural contexts.
2 Kings 24:18: Zedekiah [was] twenty and one years old when he began to reign, and he reigned eleven years in Jerusalem. And his mother's name [was] Hamutal, the daughter of Jeremiah of Libnah.
