'Peace' in the Bible

Thus saith Jehovah concerning the prophets that make my people to err; that bite with their teeth, and cry, Peace; and whoso putteth not into their mouths, they even prepare war against him:

And this man'shall be our peace. When the Assyrian shall come into our land, and when he shall tread in our palaces, then shall we raise against him seven shepherds, and eight principal men.
