(19) Thou, O Lord, remainest.--Literally, Thou sittest: i.e., as the next clause shows, upon a throne. The lamentation is drawing to its close, and the mourner finds comfort in the thought of the eternity of God (Psalm 102:12), and therefore the unchangeableness of His purpose of love towards His people.
5:17-22 The people of God express deep concern for the ruins of the temple, more than for any other of their calamities. But whatever changes there are on earth, God is still the same, and remains for ever wise and holy, just and good; with Him there is no variableness nor shadow of turning. They earnestly pray to God for mercy and grace; Turn us to thee, O Lord. God never leaves any till they first leave him; if he turns them to him in a way of duty, no doubt he will quickly return to them in a way of mercy. If God by his grace renew our hearts, he will by his favour renew our days. Troubles may cause our hearts to be faint, and our eyes to be dim, but the way to the mercy-seat of our reconciled God is open. Let us, in all our trials, put our whole trust and confidence in his mercy; let us confess our sins, and pour out our hearts before him. Let us watch against repinings and despondency; for we surely know, that it shall be well in the end with all that trust in, fear, love, and serve the Lord. Are not the Lord's judgments in the earth the same as in Jeremiah's days? Let Zion then be remembered by us in our prayers, and her welfare be sought above every earthly joy. Spare, Lord, spare thy people, and give not thine heritage to reproach, for the heathen to rule over them.
Thou, O Lord, remainest for ever,.... The same in his nature and perfections; in his grace and goodness; in his power and faithfulness; in his purposes and promises; though all things else change, are fickle and inconstant, he changes not, but abides the same, without any variableness or shallow of turning; whatever revolutions there are in the world, or alterations in the course of Providence, yet he remains firm and unalterable in his counsel and covenant; though all material things are subject to decay, and even his own sanctuary lay in ruins, yet he himself continued just as he ever was. The eternity and unchangeableness of God are of great use and comfort to his people in times of distress, and to be regarded and observed:
thy throne from generation to generation; though his throne on earth, in Jerusalem, in the temple, was thrown down, yet his throne in heaven remained unshaken; there he sits, and reigns, and rules, and overrules all things here below to his own glory and the good of his people; and this is the saints' comfort in the worst of times, that Zion's King reigns; he has reigned, and will reign, throughout all generations. The Targum is,
"the house of thine habitation in the high heavens; the throne of thy glory to the generations of generations?''
