This is what the LORD Almighty, the God of Israel, says: “Listen! I am going to bring on this city and the villages around it every disaster I pronounced against them, because they were stiff-necked and would not listen to my words.

This is the message of Chapter 19: stubbornness toward God leads to disaster.

See also Proverbs 29:1 A man who remains stiff-necked after many rebukes, will suddenly be destroyed without remedy.
