'Eighteenth' in the Bible

In the eighteenth year of the reign of King Jeroboam, Abijah became king over Judah.

In the eighteenth year of his reign, he continued his policy of purifying the land and the temple. He sent Shaphan son of Azaliah, Maaseiah the city official, and Joah son of Joahaz the secretary to repair the temple of the Lord his God.

This Passover was observed in the eighteenth year of Josiah's reign.
