In Context

4 and say unto him, Take heed, and be quiet; fear not, neither let thine heart be faint, because of these two tails of smoking firebrands, for the fierce anger of Rezin and Syria, and of the son of Remaliah.

5 Because Syria hath counselled evil against thee, Ephraim also, and the son of Remaliah, saying,

6 Let us go up against Judah, and vex it, and let us make a breach therein for us, and set up a king in the midst of it, even the son of Tabeel:

7 thus saith the Lord GOD, It shall not stand, neither shall it come to pass.

8 For the head of Syria is Damascus, and the head of Damascus is Rezin: and within threescore and five years shall Ephraim be broken in pieces, that it be not a people:

9 and the head of Ephraim is Samaria, and the head of Samaria is Remaliah's son. If ye will not believe, surely ye shall not be established.
