The above chart allows the Bible student to see approximately where each of the prophets fit into the storyline of the Old Testament. The majority of the prophets spoke during the time periods described in 1 and 2 Kings. When studying each prophet you should make sure to first read the historical background related to the time period in which the Prophet spoke/wrote. Normally, this can be determined by reading the first verse of the prophetic book. There the book will tell you, which king the prophet prophesied under. Once you have that information you can look up the section in 1 and 2 Kings where that particular King(s) is discussed and learn divinely inspired history about the time period the prophet spoke.
For example Amos 1:1 states that Amos prophesied during the reign of Jeroboam, son of Joash. By cross-referencing with Kings we are able to find the historical background for his prophecies in 2 Kings 14:23-29. There we learn that this time period was a time of military and economic prosperity for Israel, but was characterized by God as a time of continued sin. This background helps us better appreciate the words of Amos’ prophesies.
