Isaiah 62:6

I have set watchmen upon thy walls, O Jerusalem, which shall never hold their peace day nor night: ye that make mention of the Lord, keep not silence,
4

Thou shalt no more be termed Forsaken; neither shall thy land any more be termed Desolate: but thou shalt be called Hephzi–bah, and thy land Beulah: for the Lord delighteth in thee, and thy land shall be married.

5

For as a young man marrieth a virgin, so shall thy sons marry thee: and as the bridegroom rejoiceth over the bride, so shall thy God rejoice over thee.

6

I have set watchmen upon thy walls, O Jerusalem, which shall never hold their peace day nor night: ye that make mention of the Lord, keep not silence,

7

And give him no rest, till he establish, and till he make Jerusalem a praise in the earth.

8

The Lord hath sworn by his right hand, and by the arm of his strength, Surely I will no more give thy corn to be meat for thine enemies; and the sons of the stranger shall not drink thy wine, for the which thou hast laboured:

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Time-Bound Fulfillment

The verse describes an ongoing, perpetual action ("never hold their peace day nor night") rather than a prophecy with a defined duration or a specific time for its fulfillment. The mention of "day nor night" emphasizes continuous activity, not a time-bound event.
