'Fourth' in the Bible

There was a great famine in Samaria. Behold, they besieged it, until a donkey's head was sold for eighty pieces of silver, and the fourth part of a kab of dove's dung for five pieces of silver.

Yahweh said to Jehu, "Because you have done well in executing that which is right in my eyes, [and] have done to the house of Ahab according to all that was in my heart, your sons of the fourth generation shall sit on the throne of Israel."

This was the word of Yahweh which he spoke to Jehu, saying, "Your sons to the fourth generation shall sit on the throne of Israel." So it came to pass.

It happened in the fourth year of king Hezekiah, which was the seventh year of Hoshea son of Elah king of Israel, that Shalmaneser king of Assyria came up against Samaria, and besieged it.

On the ninth day of the [fourth] month the famine was severe in the city, so that there was no bread for the people of the land.
