'Fourth' in the Bible

Nevertheless, the LORD told Jehu, "Because you have done well in carrying out what I saw as the right thing to do by completing everything I had in mind regarding Ahab's dynasty, your sons will sit on the throne of Israel to the fourth generation."

In the fourth year of King Hezekiah's reign (that is, during the seventh year of Elah's son Hoshea's reign as king of Israel), King Shalmaneser from Assyria invaded Samaria and besieged it.

By the ninth day of the fourth month, the resulting famine had become so severe in the city that no food remained for the people who lived in the land.
