2 Kings 3:24

And when they came to the camp of Israel, the Israelites rose up and smote the Moabites, so that they fled before them: but they went forward smiting the Moabites, even in their country.

Cross-reference

In 1 Thessalonians 5:3, sudden destruction comes when people think peace — same false security leading to disaster as Moab's rush into battle here.

In Joshua 8:20-22, Israel ambushes Ai and surrounds them — parallels the Israelites rising up to smite Moab in this ambush.

In Judges 20:40-46, Benjamin is surrounded by an ambush — similar to the Moabites being routed after rushing into the Israelite camp here.
