I have set watchmen upon thy walls - (See the notes at Isaiah 21:6-11). The speaker here is undoubtedly Yahweh; and by watchmen he means those whom he had appointed to be the instructors of his people - the ministers of religion. The name 'watchmen' is often given to them (Ezekiel 3:17; Ezekiel 33:7; see the notes at Isaiah 52:8; Isaiah 56:10).

Which shall never hold their peace - The watches in the East are to this day performed by a loud cry as they go their rounds. This is done frequently in order to mark the time, and also to show that they are awake to their duty. "The watchmen in the camp of the caravans go their rounds, crying one after another, 'God is one; He is merciful'; and often add, 'Take heed to yourselves'" - (Tavernier). The truth here taught is, that they who are appointed to be the ministers of religion should be ever watchful and unceasing in the discharge of their duty.

Ye that make mention of the Lord - Margin, 'That are the Lord's remembrancers.' These are evidently the words of the prophet addressing those who are watchmen, and urging them to do their duty, as he had said Isaiah 62:1 he was resolved to do his, Lowth renders this, 'O ye that proclaim the name of Yahweh.' Noyes, 'O ye that praise Yahweh.' But this does not express the sense of the original as well as the common version. The Hebrew word המזכירים hamazekiyriym, from זכר zâkar, "to remember") means properly those bringing to remembrance, or causing to remember. It is a word frequently applied to the praise of God, or to the celebration of his worship Psalm 20:7; Psalm 38:1; Psalm 45:17; Psalm 70:1; Psalm 102:12. In such instances the word does not mean that they who are engaged in his service cause Yahweh to remember, or bring things to his recollection which otherwise he would forget; but it means that they would keep up his remembrance among the people, or that they proclaimed his name in order that he might not be forgotten. This is the idea here. It is not merely that they were engaged in the worship of God; but it is, that they did this in order to keep up the remembrance of Yahweh among people. In this sense the ministers of religion are 'the remembrancers' of the Lord.

Keep not silence - Hebrew, 'Let there be no silence to you.' That is, be constantly employed in public prayer and praise.

Ye that make mention of the Lord, keep not silence - The faithful, and in particular the priests and Levites, are exhorted by the prophet to beseech God with unremitted importunity (compare Luke 18:1, etc.) to hasten the redemption of Sion. The image in this place is taken from the temple service; in which there was appointed a constant watch, day and night, by the Levites: and among them this seems to have belonged particularly to the singers, see 1 Chronicles 9:33. Now the watches in the east, even to this day, are performed by a loud cry from time to time of the watchmen, to mark the time, and that very frequently, and in order to show that they themselves are constantly attentive to their duty. Hence the watchmen are said by the prophet, Isaiah 52:8, to lift up their voice; and here they are commanded, not to keep silence; and the greatest reproach to them is, that they are dumb dogs; they cannot bark; dreamers; sluggards, loving to slumber, Isaiah 56:10. "The watchmen in the camp of the caravans go their rounds crying one after another, 'God is one, he is merciful:' and often add, 'Take heed to yourselves.'" Tavernier, Voyage de Perse, 54:1 chap. 10. The hundred and thirty-fourth Psalm gives us an example of the temple watch. The whole Psalm is nothing more than the alternate cry of two different divisions of the watch. The first watch addresses the second, reminding them of their duty; the second answers by a solemn blessing. The address and the answer seem both to be a set form, which each division proclaimed, or sung aloud, at stated intervals, to notify the time of the night: -

First Chorus

"Come on now, bless ye Jehovah, all ye servants of Jehovah;

Ye that stand in the house of Jehovah in the nights;

Lift up your hands towards the sanctuary,

And bless ye Jehovah."

Second Chorus

"Jehovah bless thee out of Sion;

He that made heaven and earth."

"Ye who stand in the place of the watch, in the house of the sanctuary of the Lord; and ye praise through the nights;" - says the Chaldee paraphrase on the second line. And this explains what is here particularly meant by proclaiming, or making remembrance of, the name of Jehovah: the form, which the watch made use of on these occasions, was always a short sentence, expressing some pious sentiment, of which Jehovah was the subject; and it is remarkable, that the custom in the east in this respect also still continues the very same; as appears by the example above given from Tavernier.

And this observation leads to the explanation of an obscure passage in the Prophet Malachi, Malachi 2:12.

"Jehovah will cut off the man that doeth this;

The watchman and the answerer, from the tabernacles of Jacob;

And him that presenteth an offering to Jehovah God of hosts."

I have set watchmen upon thy walls, O Jerusalem,.... Not angels, as Jarchi; nor kings, as Kimchi; nor princes and civil magistrates, as others; nor the mourners in Zion, as Aben Ezra; but ministers of the Gospel; as the prophets of the Old Testament are called watch men, Isaiah 21:11, so ministers of the New, Isaiah 52:8 who are to watch in all things over themselves, and for the souls of men; for their good, and to guard them against that which is evil, pernicious, and dangerous, both in principle and practice, 2 Timothy 4:5. The allusion is to watchmen on the walls of cities, whose business is to keep their place and stand, and not move from it; to look out diligently, and descry an enemy, or any approaching danger, and give notice of it; and to defend the outworks of the city, and repel the enemy; all which requires courage, constancy, vigilance, and sobriety. The church is a city, and a walled one; God himself is a wall about her; salvation by Christ is as walls and bulwarks to her; and ministers of the Gospel are set for the defence of her: this is an ordinance and appointment of God; these watchmen are not of men's setting, nor do they take this office to themselves; but are placed in it by the Lord, who makes them able ministers, qualifies them for watchmen, and enables them to perform their work; and which is an instance of the love of God to his church, and of his care of it:

which shall never hold their peace day nor night; as the living creatures in Revelation 4:8, which are an emblem of Gospel ministers; who are always to be employed, and to be continually praying or preaching; the two principal branches of their ministry, Acts 6:4, they are not to be silent, but either praying in private or in public for direction and assistance in their meditations; for supply of the gifts and graces of the Spirit in their ministration, and for success in their work; and that all blessings of grace might descend on those to whom they minister: or else preaching the Gospel; being constant in season, and out of season; frequently inculcating the doctrines of Christ; constantly affirming these things; ever informing, instructing, and exhorting the people. It was Austin's wish that death might find him either praying or preaching:

ye that make mention of the Lord, keep not silence; some take this to be an address to the same persons; and they may be described as such that make mention of the Lord in their ministrations; of the grace and love of God the Father; of the person, office, and grace of Christ; and of the operations of the Spirit: or, "as the remembrancers of the Lord" (i), as it may be rendered; that put men in mind of the Lord; of what he has done for them, and is unto them; of the doctrines of the Gospel respecting him, and of their duty to him, and to one another, and to all men; and who put the Lord in mind of his promises to his people, and prophecies concerning them, to fulfil them: but I rather think another set of men are meant, even members of churches, as distinct from ministers; who make mention of the Lord to one another, in private conference with each other; of his gracious dealings with them, and favours bestowed upon them; and who make mention of him in their prayers to him, and praises of him; and who should not keep silence, but pray without ceasing, even always, and not faint, Luke 18:1.

Watchmen stationed upon the walls of Zion (says the third strophe) do not forsake Jehovah till He has fulfilled all His promise. "Upon thy walls, O Jerusalem, have I stationed watchmen; all the day and all the night continually they are not silent. O ye who remember Jehovah, leave yourselves no rest! And give Him no rest, till He raise up, and till He set Jerusalem for a praise in the earth." As the phrase hiphqı̄d ‛al signifies to make a person an overseer (president) over anything, it seems as though we ought to render the sentence before us, "I have set watchmen over thy walls." But hiphqı̄d by itself may also mean "to appoint" (2 Kings 25:23), and therefore עלח־ומתיך may indicate the place of appointment (lxx ἐπὶ τῶν τειχέων σου, upon thy walls: ̔Ιερουσαλήμ κατέστησα φύλακας). Those who are stationed upon the walls are no doubt keepers of the walls; not, however, as persons whose exclusive duty it is to keep the walls, but as those who have committed to them the guarding of the city both within and without (Sol 5:7). The appointment of such watchmen presupposes the existence of the city, which is thus to be watched from the walls. It is therefore inadmissible to think of the walls of Jerusalem as still lying in ruins, as the majority of commentators have done, and to understand by the watchmen pious Israelites, who pray for their restoration, or (according to b. Menachoth 87a; cf., Zechariah 1:12) angelic intercessors. The walls intended are those of the city, which, though once destroyed, is actually imperishable (Isaiah 49:16) and has now been raised up again. And who else could the watchmen stationed upon the walls really be, but prophets who are called tsōphı̄m (e.g., Isaiah 52:8), and whose calling, according to Ezekiel 33, is that of watchmen? And if prophets are meant, who else can the person appointing them be but Jehovah Himself? The idea that the author of these prophecies is speaking of himself, as having appointed the shōmerı̄m, must therefore be rejected. Jehovah gives to the restored Jerusalem faithful prophets, whom He stations upon the walls of the city, that they may see far and wide, and be heard afar off. And from those walls does their warning cry on behalf of the holy city committed to their care ascent day and night to Jehovah, and their testimony go round about to the world. For after Jerusalem has been restored and re-peopled, the further end to be attained is this, that Jehovah should build up the newly founded city within (cōnēn the consequence of bânâh, Numbers 21:27, and ‛âsâh, Isaiah 45:18; Deuteronomy 32:6; cf., Isaiah 54:14 and Psalm 87:5), and help it to attain the central post of honour in relation to those without, which He has destined for it. Such prophets of the times succeeding the captivity (nebhı̄'ı̄m 'achărōnı̄m; cf., Zechariah 1:4) were Haggai, Zechariah, and Malachi. Haggai stands upon the walls of Jerusalem, and proclaims the glory of the second temple as surpassing that of the first. Zechariah points from Joshua and Zerubbabel onwards to the sprout of Jehovah, who is priest and prince in one person, and builds the true temple of God. Malachi predicts the coming of the Lord to His temple, and the rising of the Sun of righteousness. Under the eyes of these prophets the city of God rose up again, and they stand upon its pinnacles, and look thence into the glorious future that awaits it, and hasten its approach through the word of their testimony. Such prophets, who carry the good of their people day and night upon their anxious praying hearts, does Jehovah give to the Jerusalem after the captivity, which is one in the prophet's view with the Jerusalem of the last days; and in so lively a manner does the prophet here call them up before his own mind, that he exclaims to them, "Ye who remind Jehovah, to finish gloriously the gracious work which He has begun," give yourselves to rest (dŏmi from dâmâh equals dâmam, to grow dumb, i.e., to cease speaking or working, in distinction from châshâh, to be silent, i.e., not to speak or work), and allow Him no rest till He puts Jerusalem in the right state, and so glorifies it, that it shall be recognised and extolled as glorious over all the earth. Prophecy here sees the final glory of the church as one that gradually unfolds itself, and that not without human instrumentality. The prophets of the last times, with their zeal in prayer, and in the exercise of their calling as witnesses, form a striking contrast to the blind, dumb, indolent, sleepy hirelings of the prophet's own time (Isaiah 56:10).

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.

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.

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

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).

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.
