The relative importance of finding 8 Bible kings on a single tablet, dwarfs the fact that it mentions the "house of David", given the fact that the Mesha stele (848 BC) and the Shishak temple (925 BC) also say "house of David".
(Hazael, Ben-Hadad II, Ahab, Ahaziah, Jehoram, Jehu, David) Hazael created his victory stele in celebration of killing the two Hebrew kings Joram and Ahaziah at Ramoth Gilead in 841 BC as recorded in 2 Kings -29.
Hazael chose Tel Dan to set up the stele because it was the most important pagan worship center in northern Israel for 617 years from 1340-723 BC.d.
It is important to note that Hazael wounded Joram but it was Jehu who actually killed Joram and Ahaziah.
The State of Israel (Hebrew: מדינת ישראל; Arabic: دولة إسرائيل) is a small yet diverse Middle Eastern country bordered by Egypt and the Gaza Strip to the southwest, by the West Bank and Jordan to the east, and by Syria and Lebanon to the north.
The country has a long coastline on the eastern Mediterranean Sea, and very limited access to the Red Sea at the Gulf of Aqaba (often called the Gulf of Eilat in Israel).
