2 Kings 24:6-8

6He passed away and his son Jehoiachin replaced him as king.

7The king of Egypt did not march out from his land again, for the king of Babylon conquered all the territory that the king of Egypt had formerly controlled between the Brook of Egypt and the Euphrates River.

8Jehoiachin was eighteen years old when he became king, and he reigned three months in Jerusalem. His mother was Nehushta the daughter of Elnathan, from Jerusalem.
