2 Chronicles 35:19 in the King James Version
In the eighteenth year of the reign of Josiah was this passover kept.
Context
18 There was no Passover like that kept in Israel from the days of Samuel the prophet, nor did any of the kings of Israel keep such a Passover as Josiah kept—with the priests, the Levites, and all Judah and Israel who were present, and the inhabitants of Jerusalem.
19 This Passover was kept in the eighteenth year of the reign of Josiah.
20 After all this, when Josiah had prepared the temple, Neco king of Egypt went up to fight against Carchemish by the Euphrates, and Josiah went out against him.
