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 -The weapons 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 fault or criticize you and accuse you of pretense 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 derivative probably from courts of justice; and the idea is, that truth and victory, in every strife of words, would be on the side of the believer.
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.
