'Denounce' in the Bible

I denounce unto you this day, that ye shall surely perish; ye shall not prolong your days in the land, whither thou passest over the Jordan to go in to possess it.

For I have heard the defaming of many, terror on every side. Denounce, and we will denounce him,'say all my familiar friends, they that watch for my fall; peradventure he will be persuaded, and we shall prevail against him, and we shall take our revenge on him.
