2. He will separate them to himself again. (1.) He will gather them in mercy out of the countries whither they were scattered, to be monuments of mercy, as the incorrigible were gathered to be vessels of wrath, v. 41. Not one of God's jewels shall be lost in the lumber of this world. (2.) He will bring them to the land of Israel, which he had promised to give to their fathers; and the discontinuance of their possession shall be no defeasance of their right; it is the land of Israel still, and thither God will bring them safely again, v. 42. (3.) He will re-establish his ordinances among them, will set up his sanctuary in his holy mountain, which is here called the mountain of the height of Israel; for, though the Mount Zion was none of the highest mountains, yet the temple there was one of the highest honours of Israel. It is promised that those who preserved their integrity, and would not serve idols, in other lands, shall return to their prosperity and shall serve the true God in their own land: All of them in the land shall serve me. Note, It is the true happiness of a people, and a sure token for good to them, when there is a prevailing disposition in them to serve God. Whereas God had forbidden the idolaters to bring their gifts to his altar, of these he will require offerings and first-fruits, and will accept them, v. 40. What he does not require he will not accept, but what is done with a regard to his precepts he will be well pleased with. He will accept them with their sweet savour, or savour of rest (v. 41), as being very grateful to him and what he takes a complacency in; whereas, to hypocritical worshippers, he says, I will not smell in your solemn assemblies. (4.) He will give them true repentance for their sins, v. 43. When they find how gracious God is to them they will be overcome with his kindness, and blush to think of their bad behaviour towards so good a God: "There, in my holy mountain, when you come to enjoy the privileges of that again, there shall you remember your doings, wherein you have been defiled." Note, The more conversant we are with God's holiness the more we shall see of the odious nature of sin. There you shall loathe yourselves in your own sight. Note, Ingenuous evangelical repentance makes people loathe themselves for their sins, as Job xlii. 5, 6. (5.) He will give them the knowledge of himself: They shall know by experience that he is the Lord, that he is a God of almighty power and inexhaustible goodness, kind to his people and faithful to his covenant with them. Note, All the favours we receive from God should lead us into a more intimate acquaintance with him. (6.) He will do all this for his own name's sake, notwithstanding their undeservings and ill-deservings (v. 44); he has wrought with them, that is, wrought for them, wrought in favour of them, wrought in concurrence with them, they doing their endeavour; he has wrought with them purely for his name's sake. His reasons were all fetched from himself. Had he dealt with them according to their wicked ways and their corrupt doings, though they were the better and sounder part of the house of Israel, he would have left them to be scattered and lost with the rest; but he recovered and restored them for the sake of his own name, not only that it might not be polluted (v. 14), but that he might be sanctified in them before the heathen (v. 41), that he might sanctify himself (so the word is); for it is God's work to glorify his own name. He will do well for his people that he may have the glory of it, that he may manifest himself to be a God pardoning sin and so keeping promise, that his people may praise him, and that their neighbours may likewise take notice of him, as they did when God burned again their captivity, Ps. cxxvi. 3. Then said they among the heathen, The Lord has done great things for them.
