I have set watchmen upon thy walls... — The “watchmen” have been differently interpreted as (1) angelic guardians and (2) prophets. Zechariah 1:12, and Daniel 10:16-21 may be alleged in favour of (1), but on the whole, (2) seems preferable. The prophets of the return from exile, Zechariah, Haggai, Malachi, may be thought of as representative examples of such “watchmen,” as also are the prophets of the Christian Church, which takes partly, at least, the position of the new Jerusalem.
Ye that make mention... — Better, ye that are the remembrancers. They are to remind Jehovah of His promises day and night, that He may hasten their fulfilment, never resting till the future Jerusalem is in very deed “a praise in the earth.” (Comp. Zechariah 1:12.)
