Isaiah 8:10

Take counsel together - This is an address to the same foreign nations. It refers to the designs which they would form to destroy the Jewish state.

Speak the word - That is, give the command - to overturn the nation of the Jews.

It shall not stand - It shall not be accomplished.

For God is with us - Hebrew ‘For Immanuel.’ It indicates the confidence of the prophet in view of the promise and the pledge. His reliance was there. Though the enemies were strong and mighty; though the confederacy was formidable; yet his simple reliance was in the name Immanuel! In this he had confidence, in spite of all the violent efforts and designs of the foes of Judah; see Numbers 14:9 :

Only, rebel not ye against the Lord:

Neither fear ye the people of the land;

For they are bread for us;

Their defense is departed from them,

And Jehovah is with us,

Fear thom not.

See also Psalms 46:6 :

The heathen raged,

The kingdoms were moved.

He uttered his voice, the earth dissolved.

Jehovah of hosts is with us;

The God of Jacob is our refuge.
