And my people shall dwell. As we have said that spiritual righteousness is that which has its seat in the hearts of men, we must say the same thing about peace, which is the fruit of it. Accordingly, when quiet habitations and resting-places are here mentioned, let us remember the saying of Paul, "justified by faith, we have peace with God." (Romans 5:1.) When Christ says that he "leaves" this peace to the disciples, (John 14:27,) he affirms that "it cannot be given by the world;" and we ought not to wonder at this, for, as the same Apostle Paul informs us in another passage, "this peace surpasses all understanding." (Philippians 4:7.) Having obtained this righteousness, we are no longer restless or alarmed within, as when we feel in the gnawings of conscience the wrath of God. A bad conscience is always alarmed, and harassed by wretched uneasiness. Wicked men must therefore be uneasy, and distressed by a variety of terrors; for where righteousness is banished that peace cannot be found; and where Christ reigns, there alone do we find true peace. Assured peace, therefore, is enjoyed by none but believers, who appeal to the heavenly tribunal, not only by their piety, but by their reliance on the mercy of God. Hence we infer that Christ does not yet reign where consciences are uneasy, and tossed by the various waves of doubts, as must be the case with Papists and all others who are not built on the sacrifice of Christ and the atonement obtained through him.

And my people shall dwell in a peaceable habitation - In cities and towns that would not be alarmed bv internal or external foes.
And in sure dwellings - In dwellings that would be secure from invasion. - All this is descriptive of the peaceful times, and the general security which followed the return from Babylon. To this period of happiness and prosperity, Isaiah, as well as the other prophets, often refers.

And my people shall dwell in a peaceable habitation,.... Jews and Gentiles, and all the saints, shall dwell in peace and love one with another, and shall be free from all the outrages and persecutions of the enemy; which, when these happy times of the pouring forth of the Spirit and of the spiritual reign of Christ come, will be no more:
and in sure dwellings; where they may dwell safely and confidently, secure from all enemies, in no fear of them, and free from all hurt and danger by them:
and in quiet resting places; where they may sleep and rest quietly, and none to disturb them, and make them afraid: and though all this may be understood of their private houses and habitations, yet may well enough be applied to the several Christian communities and churches to which they belong; where they shall enjoy much spiritual prosperity and safety, great peace and quietness, comfort and rest, under the ministry of the word, and administration of ordinances.

sure . . . quiet--free from fear of invasion.
