Isaiah 7:5 Meaning

3Then said the LORD unto Isaiah, Go forth now to meet Ahaz, thou, and Shear-jashub thy son, at the end of the conduit of the upper pool in the highway of the fuller's field;

4And say unto him, Take heed, and be quiet; fear not, neither be fainthearted for the two tails of these smoking firebrands, for the fierce anger of Rezin with Syria, and of the son of Remaliah.

5Because Syria, Ephraim, and the son of Remaliah, have taken evil counsel against thee, saying,

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

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