God is in the midst of her; she shall not be moved. The Psalmist now shows that the great security of the Church consists in this, that God dwells in the midst of her; for the verb which we translate, shall be moved, is of the feminine gender, nor can it be referred to God, as if it were designed to teach that God is immovable. The sentence must be explained in this way, The holy city shall not be moved or shaken, because God dwells there, and is always ready to help her. The expression, the dawn of the morning [1] denotes daily, as soon as the sun rises upon the earth. The sum of the whole is, If we desire to be protected by the hand of God, we must be concerned above all things that he may dwell amongst us; for all hope of safety depends upon his presence alone. And he dwells amongst us for no other purpose than to preserve us uninjured. Moreover, although God does not always hasten immediately to our aid, according to the importunity of our desires, yet he will always come to us seasonably, so as to make apparent the truth of what is elsewhere said, "Behold, he that keepeth Israel shall neither slumber nor sleep," (Psalm 121:4.)

Footnotes

1 - "At the looking forth of the morning; that is, as the Greek explaineth it, very early;' when the morning peereth or showeth the face." -- Ainsworth. "As soon as the morning appears [or shows] its face; i.e., God will come very early to her succor, before any enemy is awakened to annoy her." -- Mudge. "Before the dawn of the morning; i.e., with the utmost readiness and alacrity. The expression is borrowed from the conduct of a person who, in his anxiety to accomplish a favorite object, engages in it earlier than men ordinarily would. Jeremiah 7:13; and 7:25." -- French and Skinner.

God is in the midst of her - God is in the midst of the "city" referred to above - the "city of God." That is,
(a) he dwelt there by the visible symbol of his presence, the Shekinah;
(b) he was there "actually" as a help and a protector.
It was his chosen abode, and as long as such a Being dwelt in the city, they had nothing to fear.
God shall help her - That is, in her danger, he will interpose to save her. This is language such as would be used in reference to a place that was besieged, and would well apply to the state of things when Jerusalem was besieged by the armies of Assyria under Sennacherib. The language expresses the confidence of the people in the time of the impending danger.
And that right early - Margin, "when the morning appeareth." Literally, "in the faces of the morning," as the word is commonly used; or, more literally, in the "turning" of the morning - for the verb from which the word is derived means properly "to turn," and then "to turn to or from any one." The noun is applied to the face or countenance, because the person is "turned" to us when we see his countenance. The poetic idea here seems to refer to the day as having turned away "from" us at night, and then as turning about "toward" us in the morning, after having gone, as it were, to the greatest distance from us. "Possibly" there may be an allusion here to what occurred in the camp of the Assyrians, when the discovery that the angel of the Lord had smitten them was made early in the morning, or when men arose in the morning: "The angel of the Lord went forth, and smote in the camp of the Assyrians an hundred and fourscore and five thousand: and when they arose in the morning" (that is, when men arose in the morning), "behold, they were all dead corpses," Isaiah 37:36.

God is in the midst of her - God will not abandon them that trust in him; he will maintain his own cause; and, if his Church should at any time be attacked, he will help her and that right early - with the utmost speed. As soon as the onset is made, God is there to resist. As by the day-break the shadows and darkness are dissipated; so by the bright rising of Jehovah, the darkness of adversity shall be scattered.

God [is] in the midst of her; she shall not be moved: God shall help her, [and that] (f) right early.
(f) Always when need requires.

God is in the midst of her,.... The church and people of God; not merely by his essence, power, and providence, as he is in the midst of the world; but by his gracious presence, and which always continues, though not always perceived; and is a sufficient antidote against all fear of men and devils;
she shall not be moved; though the earth may; and when it is, Psalm 46:2, neither from the heart of God, on which his people are set as a seal; nor from the hands of Christ, from whence they can never be plucked; nor from the covenant of grace, which is immovable; nor off of the rock Christ, on which they are built; nor from the state of grace, of justification, adoption, and sanctification, in which they stand; nor out of the world, by all the cunning and power of antichrist;
God shall help her, and that right early: or "when the morning looks out" (x). When it is night with the church, it is the hour and power of darkness with the enemies of it; and this is the time of the reign of antichrist, whose kingdom is a kingdom of darkness: but the "morning cometh, and also the night"; the former being about to break forth, and the latter to be at an end; yea, at eventide it shall be light: and the Lord will be a suitable, seasonable, and timely help to his people; for though weeping endures the night, joy comes in the morning.
(x) "respiciente mane", Pagninus; "ad prospectum aurorae", Musculus; "at the looking forth of the morning", Ainsworth; that is, "speedily and quickly", as Suidas interprets it in voce

right early--literally, "at the turn of morning," or change from night to day, a critical time (Psalm 30:5; compare Isaiah 37:36).
