'Exterminate' in the Bible

"Now as to the prophet, if through deceit he delivers a message, I the LORD have deceived that prophet! I'll reach out in opposition to him and exterminate him from among my people Israel.

"I'm going to seek both the lost as well as the scattered, and bring them both back so their broken bones can be set and the sick can be healed. But in righteousness I'll exterminate the fat and the stiff-necked.'"
