'Thoroughly' in the Bible

When they approached the Israelite camp, the Israelites rose up and struck down the Moabites, who then ran from them. The Israelites thoroughly defeated Moab.

And all the people of the land went into the house of Baal, and brake it down; his altars and his images brake they in pieces thoroughly, and slew Mattan the priest of Baal before the altars. And the priest appointed officers over the house of the LORD.

You thoroughly defeated Edom and it has gone to your head! Gloat over your success, but stay in your palace. Why bring calamity on yourself? Why bring down yourself and Judah along with you?"
