Take counsel. After having spoken of the forces of the enemies, he now comes to their counsels; as if he had said, "Although the enemies may abound not only in armor and in strength, but, in counsel and wisdom, still they will accomplish nothing." And this warning was very necessary; for it often happens that we despise enemies, though powerful and well armed, because they want counsel, and are guided by blind violence rather than by reason. He therefore forewarns them that the craftiness of the enemies, and all the arts by which they endeavor to gain advantage over the people of God, will in the end be unsuccessful; and, therefore, that they will accomplish nothing, though they be in want of nothing, and though they may have a great abundance of everything, of forces, and counsels, and crafty designs. He adds -- Speak the word. To make the meaning more clear, I have rendered it decree a decree. This relates to their insolence, or it is the conclusion of the consultation; for after deliberation a decree usually follows. He declares that all these things will vanish into smoke. It is, therefore, sufficiently evident what the Prophet means, and to what purpose this passage ought to be applied; for it may be regarded as a shield by which we can drive away all the terrors of enemies, whether they excel, on the one hand, in forces, wealth, power, influence, and rank; or, on the other, in wisdom, counsel, craftiness, sagacity, and invention, or, in a word, in insolence. For we are well armed and very powerful, if God is with us; and, therefore, all the contrivances or decrees of adversaries will immediately vanish away. For God is with us. ky mnv 'l, (ki Immanu-el;) literally, for Immanuel. We have already explained the force of this argument. [1] For my own part, I have no doubt that he alludes to the name which he formerly gave to Christ; for although he means that God assists his people, yet as the majesty of God is not of itself sufficient to support us, he contemplates God himself in the person of the Mediator, in whom alone he has promised to assist us.

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 Psalm 46:6-7 :
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.

Take counsel together,.... As Rezin king of Syria, and Remaliah's son, did against Judah, Isaiah 7:5,
it shall come to nought; for, though they came up against it, they could not overcome it, 2-Kings 16:5,
speak the word; what they intended, resolved upon, and determined to do; this is the issue of their counsels:
and it shall not stand; See Gill on Isaiah 7:7,
for God is with us; which is the interpretation of the name "Immanuel": and which shows that the reason why the consultations and resolutions of the enemies of Judah could not take place, so as to destroy it, was because Immanuel, the virgin's son, was to be born in it.

the word--of command, for the assault of Jerusalem.
God is with us--"Immanuel" implies this (Numbers 14:9; Psalm 46:7).
