Violence shall no more be heard in thy land, wasting nor destruction within thy borders; but thou shalt {s} call thy walls Salvation, and thy gates Praise.

(s) Meaning not an earthly happiness, but spiritual, which is fulfilled in Christ's kingdom.

Wesley's Notes

60:18 Salvation - They shall be safe, and able to defend thee; thou shalt be as safe, as salvation itself can make thee. Thy gates - Within and upon thy gates and walls, thou shalt sing praises. All this will be fulfilled during the thousand years wherein Christ shall reign upon earth.

Jamieson-Fausset-Brown Bible Commentary

18. (Isa 2:4). Not only shall thy walls keep thee safe from foes, but "Salvation" shall serve as thy walls, converting thy foes into friends, and so ensuring thee perfect safety (Isa 26:1, 2).

gates-once the scene of "destruction" when victorious foes burst through them (Ne 1:3); henceforth to be not only the scene of praises, but "Praise" itself; the "gates," as the place of public concourse, were the scene of thanksgivings (2Ch 31:2; Ps 9:14; 24:7; 100:4). "Judah," the favored tribe, means "praise."

Matthew Henry's Concise Commentary

60:15-22 We must look for the full accomplishment in times and things, exceeding those of the Old Testament church. The nations and their kings shall lay themselves out for the good of the church. Such a salvation, such a redemption, shall be wrought out for thee, as discovers itself to be the work of the Lord. Every thing shall be changed for the better. In thy land shall no more be heard threats of those that do violence, nor complaints of those that suffer violence. Thy walls shall be means of safety, thy gates shall be written upon with praises to God. In the close of this chapter are images and expressions used in the description of the New Jerusalem, Re 21:23; 22:5. Nothing can answer to this but some future glorious state of the church on earth, or the state of the church triumphant in heaven. Those that make God their only light, shall have him their all-sufficient light. And the happiness shall know no change or alloy. No people on earth are all righteous; but there are no mixtures in heaven. They shall be wholly righteous. The spirits of just men shall there be made perfect. The glory of the church shall be to the honour of God. When it shall be finished, it will appear a work of wonder. It may seem too difficult to be brought about, but the God of almighty power has undertaken it. It may seem to be delayed and put off; but the Lord will hasten it in the time appointed by his wisdom, though not in the time prescribed by our folly. Let this hope cheer us under all difficulties, and stir us up to all diligence, that we may have an abundant entrance into this everlasting kingdom of our Lord and Saviour Jesus Christ.
