Mesha in Wikipedia
The books of Samuel record that Moab was conquered by David (floruit c.1000-970 BCE) and retained in the territories of his son Solomon (d. 931 BCE). Later, King Omri of Israel reconquered Moab after Moab was lost subsequent to King Solomon's reign. The Mesha Stele, erected by Mesha, indicates that it was Omri, king of the northern kingdom of Israel, who conquered his land. The Mesha Stele records Mesha's liberation of Moab c.850 BCE.
2 Kings 3:4 reports the same events from the point of view of the Israelites, stating that "King Mesha of Moab ... used to deliver to the king of Israel one hundred thousand lambs, and the wool of one hundred thousand rams", before rebelling against Jehoram (the Mesha Stele does not name the king against whom Mesha rebelled). 2 Kings and the Mesha Stele differ in their explanation for the success of the revolt: according to Mesha, "Israel has been defeated", but 2 Kings says the Israelites withdrew voluntarily when Mesha sacrificed his own son to his god Chemosh. Aside from these attestations, references to Mesha are scanty, if extant.
