King Mesha of Moab
This guy leads a revolt against Israel and Judah, re-establishing his dominance over Moab, which had been conquered earlier by Omri. He makes good headway at first, but ultimately provokes the Israelites to destroy his kingdom—almost the point of annihilation.
However, when he sacrifices his first-born son to the god Chemosh, it somehow repels the Israelite invasion. Some sort of "wrath" falls on the Israelites and they leave. The Biblical narrators probably considered this to be a kind of repugnance at the actions of Mesha, rather than the actual wrath of Chemosh (who in their view, probably wasn't real).
