They who confide in Jehovah are as mount Zion. The present Psalm differs from the preceding in this -- that while in the other it was said that the Church had been preserved by the power of God, without any human means, the Holy Spirit, in the one before us, teaches that in the time to come she shall always continue in perfect safety, because she is defended by the invincible power of God. When the Church is emblematically described by the situation of the city of Jerusalem, the design of the Prophet is to encourage each of the faithful to believe, that the safety promised in common to all the chosen people belongs to him. But in exhibiting to the eyes a visible image of the Church, he accommodates himself to the rudeness of those who, detained by the dulness of the flesh, still continue settled down in the earth. It ought then, in the first place, to be noticed, that to those who may not sufficiently apprehend by faith the secret protection of God, the mountains which environ Jerusalem are exhibited as a mirror, in which they may see, beyond all doubt, that the Church is as well defended from all perils, as if it were surrounded on all sides with like walls and bulwarks. Moreover, it is profitable to know what I have just now touched upon -- that whenever God speaks to all his people in a body, he addresses himself also to each of them in particular. As not a few of the promises are extended generally to the whole body of the Church, so many contemplate them as at a distance, as far removed from them, and will not presume to appropriate them to themselves. The rule here prescribed must therefore be observed, which is, that each apply to himself whatever God promises to his Church in common. Nor does the Psalmist without cause make Jerusalem a representation of the Church, for the sanctuary of God and the ark of the covenant were there. With respect to the explanation of the words, it is to be observed that the last two verbs of the first verse may be understood in two ways. They may both be governed by Jerusalem as the nominative. But some understand the first verb, l' ymvt al, lo yimmot, shall not be removed, only as spoken of Jerusalem and the latter verb, ysv, yesheb, shall abide, as referring to the faithful, so that according to this view there is a change of number, which is very common among the Hebrews -- the singular number, ysv, yesheb, being used instead of the plural, ysvv, yeshbu. And certainly the sentence might not improperly be translated thus: They who trust in Jehovah, as mount Zion shall not be removed, shall dwell for ever, or continue steadfast, for the verb translated to abide is taken in this sense. We now perceive the meaning of the Prophet, which is, that although the world is subject to so many and so sudden changes as almost to put on a new face every moment, and although the faithful are mingled with and placed in the same external condition as others, yet their safety continues steadfast under the invincible protection of God. Not that they are permitted to dwell undisturbed and at ease; but because their safety being under the guardianship of God is assaulted in vain; at least they can never altogether fall, although they may stumble. But let us notice that the word hvmchym, habbtechim, which signifies, those who hope or wait for, conveys an implicit injunction to steadfastness of faith. Whoever, then, desires to be sustained by the hand of God, let him constantly lean upon it; and whoever would be defended by it, let him patiently repose himself under it. When God suffers us to be often carried hither and thither, or driven about like chaff by the wind, this comes to pass through our own inconstancy -- because we prefer fluttering in the air to fixing our minds on the rock of his help. The similitude employed in the second verse is abundantly plain, teaching us, that as the continuous chain of mountains round about Jerusalem exhibits the appearance of walls, so God encompasses the faithful by his power, to ward off from them all harm. [1] Similar forms of expression are frequently to be met with in the Scriptures' God often promises to be a wall and a fore-wall to his people. But David, or whoever was the author of the psalm, proceeds still farther, showing under the figure of mountains the secret protection with which God defends his own people, to the end that the ignorant and feeble-minded who are still held down to the earth by their own dulness of understanding, aided by the sight of the mountains, may raise their minds upwards to the conception and contemplation of heavenly things.

Footnotes

1 - From the mountains or hills which surrounded Jerusalem, the Prophet Ezekiel (Ezekiel 11:3) represents it under the image of a "cauldron."

They that trust in the Lord - His people; his friends. It is, and has been always, a characteristic of the people of God that they trust or confide in him.
Shall be as mount Zion - The mountain which David fortified, and on which the city was at first built, 2-Samuel 5:6-9. The name Zion became also the name by which the entire city was known.
Which cannot be removed, but abideth for ever - A mountain is an emblem of firmness and stability; and it is natural to speak of it as that which could not be removed. There is something more than this, however, intended here, as there is some ground of comparison especially in regard to Mount Zion. This must have been either the idea that Zion was particularly strong by position, or that it was under the divine protection, and was therefore safe. Most probably it refers to Zion as a place secure by nature, and rendered more so by art.

They that trust in the Lord - Every faithful Jew who confides in Jehovah shall stand, in those open and secret attacks of the enemies of God and truth, as unshaken as Mount Zion; and shall not be moved by the power of any adversary.

"A Song of degrees." They that trust in the LORD [shall be] as mount Zion, [which] cannot (a) be removed, [but] abideth for ever.
(a) Though the world is subject to mutations, yet the people of God will stand sure and be defended by God's providence.

They that trust in the Lord shall be as Mount Zion,.... Who trust not in themselves, and in their own hearts; nor in anything of theirs, their strength or wisdom, riches or righteousness; nor in any creature whatever, in the mightiest or best of men; but in the Lord; in God, as the God of nature and providence, for all temporal mercies; and in him, as the God of grace, for all spiritual and eternal ones; who should be trusted in at all times, whether of affliction, temptation, or darkness; for which there is abundant reason. The Targum is,
"the righteous that trust in the Word of the Lord;''
in Christ the essential Word, who is trusted in by all that know him, and that know there is salvation in him, and in no other: these trust in him for acceptance with God, for a justifying righteousness, for remission of sin, for all supplies of grace, and for eternal life; and such are like Mount Zion for many things, being beloved and chosen of God, enjoying his presence, and the blessings of his grace; and being the joy of the whole earth, and a perfection of beauty; but here for their firmness and stability, as follows. Arama observes, that Mount Zion is made mention of, because here the prophecy was given; to which may be added, the psalmist was upon it, and had it in view, when he compared those that trust in the Lord unto it;
which cannot be removed, but abideth for ever: either, which Mount Zion is immovable, and continually abides, for which reason the church and people of God are compared unto it; or everyone of those that trust in the Lord, like that, can never be removed, but always abide: they can never be removed from the Lord, though they may be removed from his house and ordinances, as sometimes David was; and from his gracious presence, and sensible communion with him, and out of the world by death; yet never from his heart's love, nor out of the covenant of his grace, which is sure and everlasting; nor out of his family, into which they are taken; nor from the Lord Jesus Christ, nor out of his hands and arms, nor from off his heart; nor from off him, the foundation on which they are laid; nor out of a state of grace, either regeneration or justification; but such abide in the love of God, in the covenant of his grace, in the hands of his Son, in the grace wherein they stand, and in the house of God for evermore.

All those minds shall be truly stayed, that are stayed on God. They shall be as Mount Zion, firm as it is; a mountain supported by providence, much more as a holy mountain supported by promise. They cannot be removed from confidence in God. They abide for ever in that grace which is the earnest of their everlasting continuance in glory. Committing themselves to God, they shall be safe from their enemies. Even mountains may moulder and come to nothing, and rocks be removed, but God's covenant with his people cannot be broken, nor his care of them cease. Their troubles shall last no longer than their strength will bear them up under them. The rod of the wicked may come, may fall upon the righteous, upon their persons, their estates, their liberties, their families names, on any thing that falls to their lot; only it cannot reach their souls. And though it may come upon their lot, it shall not rest thereon. The Lord will make all work together for their good. The wicked shall only prove a correcting rod, not a destroying sword; even this rod shall not remain upon them, lest they distrust the promise, thinking God has cast them off.

God honors the confidence of His people, by protection and deliverance, and leaves hypocrites to the doom of the wicked. (Psalm 125:1-5)
Mount Zion--as an emblem of permanence, and locality of Jerusalem as one of security, represent the firm and protected condition of God's people (compare Psalm 46:5), supported not only by Providence, but by covenant promise. Even the mountains shall depart, and the hills be removed, but God's kindness shall not depart, nor His covenant of peace be removed (Isaiah 54:10).
They that trust--are "His people," (Psalm 125:2).

The stedfastness which those who trust in Jahve prove in the midst of every kind of temptation and assault is likened to Mount Zion, because the God to whom they believingly cling is He who sits enthroned on Zion. The future ישׁב signifies: He sits and will sit, that is to say, He continues to sit, cf. Psalm 9:8; Psalm 122:5. Older expositors are of opinion that the heavenly Zion must be understood on account of the Chaldaean and the Roman catastrophes; but these, in fact, only came upon the buildings on the mountain, not upon the mountain itself, which in itself and according to its appointed destiny (vid., Micah 3:12; Micah 4:1) remained unshaken. in Psalm 125:2 also it is none other than the earthly Jerusalem that is meant. The holy city has a natural circumvallation of mountains, and the holy nation that dwells and worships therein has a still infinitely higher defence in Jahve, who encompasses it round (vid., on Psalm 34:8), as perhaps a wall of fire (Zac 2:5), or an impassably broad and mighty river (Isaiah 33:21); a statement which is also now confirmed, for, etc. Instead of inferring from the clause Psalm 125:2 that which is to be expected with לכן, the poet confirms it with כי by that which is surely to be expected.
