I have set watchmen upon thy walls. "The Servant" has appointed watchers upon the walls of Zion—either "prophets" (Delitzsch), or "priests and prophets" (Kay), or, more probably, "angelic beings" (Cheyne), who keep perpetual watch and ward (Comp.
Isaiah 52:8). Neither day nor night do they hold their peace, or keep silence, but ever intercede with God for his people, like the "angel of Jehovah" in Zechariah 1:12, reminding him of his covenant with them, and his promises to them, and exhorting him to "awake, awake" for his own honour's sake (Isaiah 51:9-11).
It is generally allowed that the "watchers" in Daniel 4:13, Daniel 4:17, Daniel 4:23 are angels; and the same interpretation best suits the "watchmen" of the present passage. Ye that make mention of the Lord; rather, as in the margin, ye that are the Lord's remembrancers; i.
e. "ye whose business it is to call to God's remembrance the needs and claims of his people, and the obligations of his covenant promises."
