'Fourth' in the Bible

There was a great famine in Samaria; and behold, they besieged it, until a donkey’s head was sold for eighty shekels of silver, and a fourth of a kab of dove’s dung for five shekels of silver.

The Lord said to Jehu, “Because you have done well in executing what 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 is the word of the Lord which He spoke to Jehu, saying, “Your sons to the fourth generation shall sit on the throne of Israel.” And so it was.

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

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