No weapon that is formed - No instrument of war, no sword, or spear; no instrument of persecution or torture that is made by the smith, Isaiah 54:16.

Shall prosper - On the meaning of this word, see the notes at Isaiah 52:13. The sense here is, that it shall not have final and ultimate prosperity. It might be permitted for a time to appear to prosper - as persecutors and oppressors have done; but there would not be final and complete success.

And every tongue - No one shall be able to injure you by words and accusations. If a controversy shall arise; if others reproach you and accuse you of imposture and deceit, you will be able ultimately to convince them of error, and, by manifestation of the truth, to condemn them. The language here is derived probably from courts of justice (see the notes at Isaiah 41:1); and the idea is, that truth and victory, in every strife of words, would be on the side of the church. To those who have watched the progress of discussions thus far on the subject of the true religion, it is needless to say that this has been triumphantly fulfilled. Argument, sophism, ridicule, have all been tried to overthrow the truth of the Christian religion. Appeals have been made to astronomy, geology, antiquities, history, and indeed to almost every department of science, and with the same want of success. Poetry has lent the charm of its numbers; the grave historian has interwoven with the thread of his narrative covert attacks and sly insinuations against the Bible; the earth has been explored to prove that' He who made the world and revealed its age to Moses was mistaken in its age;' and the records of Oriental nations, tracing their history up cycles of ages beyond the Scripture account of the creation of the world, have been appealed to, but thus far in all these contests ultimate victory has declared in favor of the Bible. And no matter from what quarter the attack has come, and no matter how much learning and talent have been evinced by the adversaries of the Bible, God has raised up some Watson, or Lardner, or Chalmers, or Buckland, or Cuvier, or Wiseman, to meet these charges, and to turn the scales in favor of the cause of truth. They who are desirous of examining the effects of the controversy of Christianity with science, and the results, can find them detailed with great learning and talent in Dr. Wiseman's Lectures on the connection between Science and Revealed Religion, Andover, 1837.

This is the heritage - The inheritance which awaits those who serve God is truth and victory. It is not gold and the triumph of battle. It is not the laurel won in fields of blood. But it is, the protection of God in all times of trouble; his friendship in all periods of adversity; complete victory in all contests with error and false systems of religion; and preservation when foes rise up in any form and endeavor to destroy the church, and to blot out its existence and its name.

And their righteousness is of me - Or rather, 'this is the righteousness, or the justification which they obtain of me; this is that which I impart to them as their justification.' The idea is not that their righteousness is of him, but that this justification or vindication from him is a part of their inheritance and their portion.

No weapon that is formed against thee shall prosper,.... All weapons of war, as the Targum, which are made with a design to hurt and destroy the people of God, shall be rendered useless; not one of them shall prosper to the advantage of their enemies, or so as to answer their design; nor to the hurt and prejudice, ruin and destruction, of the saints:

and every tongue that shall rise against thee in judgment; that shall raise any calumny upon thee, or bring any charge against thee, or enter into a lawsuit with thee, litigate a point with thee in any court of judicature, or claim, in right and law, a power, authority, and dominion over thee, as the pope of Rome does over the consciences of men:

thou shalt condemn; disprove and roll off the calumny, refute the charge and accusation, put to silence the clamours and pretences of wicked men, carry the cause against them, and shake off the yoke of bondage they would bring them under; and, instead of being condemned by them, condemn them. By "weapon" may be meant all the attempts made by force to ruin the interest and church of Christ in the world, such as the bloody persecutions of the Roman emperors, who, though they made sad havoc of the professors of Christianity, and designed hereby to have rooted it out of the world, and thought they should have accomplished it, yet could not do it; so far from it, that the Christians yet more and more increased, insomuch that it became a common saying, that the blood of the martyrs was the seed of the church; also the wars of the Papists with the Albigenses and Waldenses, and all the cruel methods they have taken by fire and faggot, and the bloody inquisition, to hinder the growth of what they call heresy; yet all have been in vain, a reformation has taken place, and many nations have embraced the truth, and shook off the yoke of Popery; together with all their efforts since to crush the Protestant interest; and though the kings of the earth will be stirred up, and gather together to the battle of the Lord God Almighty, they will not succeed, but be overcome and slain, and the beast and false prophet at the head of them will be taken and cast alive into the lake of fire: and by the "tongue" may be designed the edicts of the Pagan emperors, forbidding the exercise of the Christian religion, and threatening the preachers and professors of it with imprisonment, confiscation of goods, and death itself; and the anathemas, bulls, and interdicts of the popes of Rome, as well as the reproaches, scandals, and calumnies uttered by the emissaries of that church against all that depart from it; together with the errors and heresies of false teachers of all sorts in all ages of the world, which, though levelled against the faith and doctrine of the church of Christ, have not been able to subvert it, nor ever will:

this is the heritage of the servants of the Lord; this, with all that is said in this chapter, is the part, portion, and privilege, that such shall enjoy who serve the Lord Christ, and not antichrist; they shall be treated rather as sons than as servants, and have an inheritance assigned them; not only protection from all enemies, and absolution from all charges, but they shall receive the reward of the inheritance in heaven, that which is incorruptible and undefiled, and reserved there, since they serve the Lord Christ:

and their righteousness is of me, saith the Lord; the vindication of their righteousness, of their cause, and of their character; or the reward of their righteous works in a way of grace; even all that righteousness and true holiness that is in them, and that righteousness which is imputed to them, and by which they are justified, are from the Lord; by which they are secured from all the charges of law and justice, and, from all the accusations of men and devils, and which will answer for them in a time to come, and acquit them at the bar of God before men and angels; see Romans 8:33.

No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD.

54:17 Condemn - And I will deliver thee not only from the fury of war, but also from the strife of tongues. This - This blessed condition, is the portion allotted them by me. Righteousness - The reward of their righteousness. Of me - I give it, and I will continue it to them.

17. tongue . condemn-image from a court of justice. Those who desire to "condemn" thee thou shalt "condemn" (Ex 11:7; Jos 10:21; Ps 64:8; Ro 8:1, 33).

righteousness . of me-(Isa 45:24; 46:13). Rather, "(this is) their justification from Me." Their enemies would "condemn" them, but I justify and vindicate them, and so they condemn their enemies.

54:11-17 Let the people of God, when afflicted and tossed, think they hear God speaking comfortably to them by these words, taking notice of their griefs and fears. The church is all glorious when full of the knowledge of God; for none teaches like him. It is a promise of the teaching and gifts of the Holy Spirit. All that are taught of God are taught to love one another. This seems to relate especially to the glorious times to succeed the tribulations of the church. Holiness, more than any thing, is the beauty of the church. God promises protection. There shall be no fears within; there shall be no fightings without. Military men value themselves on their splendid titles, but God calls them, Wasters made to destroy, for they make wasting and destruction their business. He created them, therefore he will serve his own designs by them. The day is coming when God will reckon with wicked men for their hard speeches, Jude 1:15. Security and final victory are the heritage of each faithful servant of the Lord. The righteousness by which they are justified, and the grace by which they are sanctified, are the gift of God, and the effect of his special love. Let us beseech him to sanctify our souls, and to employ us in his service.
