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

(h) Prophets, pastors and ministers.

(i) He exhorts the ministers never to cease to call on God by prayer for the deliverance of his Church and to teach others to do the same.

Wesley's Notes

62:6 Day nor night - There shall be a vigilant and industrious ministry. Ye - That is, are his servants. And here especially are meant his servants in ordinary, his remembrancers, such as put God in mind of his promise, and such as make the Lord to be remembered, putting his people in mind of him.

King James Translators' Notes

make...: or, are the LORD's remembrancers

Jamieson-Fausset-Brown Bible Commentary

6. I-Isaiah speaking in the person of the Messiah.

watchmen upon . walls-image from the watches set upon a city's wall to look out for the approach of a messenger with good tidings (Isa 52:7, 8); the good tidings of the return of the Jewish exiles from Babylon, prefiguring the return from the present dispersion (compare Isa 21:6-11; 56:10; Eze 3:17; 33:7). The watches in the East are announced by a loud cry to mark the vigilance of the watchmen.

ye that . mention . Lord-Hebrew, "ye that are the Lord's remembrancers"; God's servants who by their prayers "put God in remembrance" of His promises (Isa 43:26); we are required to remind God, as if God could, which He cannot, forget His promises (Ps 119:49; Jer 14:21).

Matthew Henry's Concise Commentary

62:6-9 God's professing people must be a praying people. He is not displeased with us for being earnest, as men commonly are; he bids us to cry after him, and give him no rest, Lu 11:5,6. It is a sign that God is coming to a people in mercy, when he pours out a spirit of prayer upon them. See how uncertain our creature-comforts are. See also God's mercy in giving plenty, and peace to enjoy it. Let us delight in attending the courts of the Lord, that we may enjoy the consolations of his Spirit.
