2 Ki. 15: As The World Turns

2 Kings 15:29 "In the time of Pekah king of Israel, Tiglath-Pileser king of Assyria came and took Ijon, Abel Beth Maacah, Janoah, Kedesh and Hazor. He took Gilead and Galilee, including all the land of Naphtali, and deported the people to Assyria." 

This chapter briefly lists several kings of Israel, and a couple kings of Judah. None of them appear to have done anything really noteworthy. They were evil, killed pregnant women, lost a lot of land...you know...generally clowns.

Judah

Azariah (Uzziah) - Took the throne at 16, reigned 52 years. Was apparently good. Didn't remove the high places for offerings. Was afflicted with leprosy, and Jotham took care of the day-to-day operations of the kingshippery. That's a long time to have leprosy. I suppose any length of time is, but...

Jotham - Took the throne at 25, reigned 16 years. What is with these people not removing the high places? That seems to be the one thing keeping a king from having a truly great reign. Succeeded by his son Ahaz.

Israel

Zechariah - Reigned 6 months. Generally evil. This was the fourth and final generation removed from Jehu, as Elisha prophesied. And sure enough, he was assassinated publicly by Shallum, who assumed power.

Shallum - Reigned 1 month. Probably didn't have time to be evil or good, but I would assume he would have been evil, had the brutal Mehahem not overthrown him.

Menahem - Reigned 10 years. Ripped open the pregnant women of Tiphsah because they wouldn't open their gates to his marauders. Menahem was the first democrat, because he taxed the wealthy men. This money was used to pay off Pul, the invading Assyrian king. 

Pekahiah - Reigned 2 years, did evil. Besides his name sounding like someone telling a Black-rumped Flameback what to do, Pekahiah was assassinated in the palace by one of his chief officers, Pekah, who assumed the throne.

Pekah - Reigned 20 years, did evil. Pekah had a lot of trouble with the invading Assyrians. The king, Tiglath-Peliser took a bunch of land, and deported a bunch of land, and deported people to his land. Perhaps a nod to Dt 4:7. Hoshea follows the assassination trend, and kills Pekah, assuming the throne.

So this is the common thread between Israel and Judah. Israel refused to not be like Jeroboam, and Judah wouldn't centralize the offerings and sacrifices. Where were their priests?
