This is the only known picture of an Israelite king in the world, King Jehu.
2 Kings chapters 9 and 10 tell how Jehu was ‘anointed’ king of Israel by Elisha’s messenger, and commanded to cut off the evil Omride dynasty around 841B.C.
The obelisk supplies extra detail not in the Bible. Jehu, early on in his reign, attempted to placate Assyria by paying tribute to Shalmeneser III.
Significance of the stelae: scholars were forced to challenge their view of the Bible as a book written from oral tradition with invented characters.
This was made possible by the breakthrough in Cuneiform translation in 1842, allowing translation of thousands of such Cuneiform texts.
