II Kings looks at the kingdoms of Judah and Israel.
The twelfth book in the Bible is the Second book of Kings. It continues on from the First Book of Kings and tells us more of the history of Israel and Judah. Both kingdoms are on a downward spiral of sin which ends with God's judgement and the handing over of both nations into foreign captivity.
II Kings 9:36-37
