For God will save Zion - See the notes at Psalm 51:18. That is, he will save his people; he will protect and defend them. This expresses the confident assurance of the psalmist that, whatever might be the existing troubles, God would not forsake his people, but would interpose in their behalf.

And will build the cities of Judah - Though they may now lie waste, or be desolate. See the notes at Psalm 51:18. The general idea here is, that God would be favorable to his land; that he would give success and prosperity to his people; that he would manifest his mercy to them. There is no necessity from the language used here to suppose, as DeWette and Rosenmuller do, that there is an allusion to the time of the exile, and to the restoration of the Jews from Babylon, and that consequently either the whole psalm must have been composed at that time - or (as Rosenmuller supposes) that the last verses of the psalm were added by a later hand, and that thus the whole psalm was adapted to the time of the exile. From Psalm 69:9 it would seem that, when the psalm was composed, the place of public worship was still standing, and the language here, as in Psalm 51:18, is so general that it might have been employed at any time.

That they may dwell there ... - That his people may dwell there according to the ancient promise. The idea is, that he would be the protector of his people, and that all his promises to them would be fulfilled.

God will save Zion - This fixes the Psalm to the time of the captivity. There was no Zion belonging to the Jews in the time of Saul, when those suppose the Psalm to be written who make David the author; for David after he came to the throne, won the stronghold of Zion from the Jebusites. 2 Samuel 5:7; 1 Chronicles 11:5.

Will build the cities of Judah - This refers to the return from the captivity, when all the destroyed cities should be rebuilt, and the Jews repossess their forfeited heritages. Some apply this to the redemption of the human race; and suppose that Zion is the type of the Christian Church into which the Gentiles were to be called. What evangelists and apostles apply to our Lord, we safely may. What others see so clearly in this Psalm relative to Gospel matters, I cannot discern.

For God will save Zion,.... The church of Christ, as it is often called; See Gill on Psalm 2:6; this is to be understood not so much of the salvation of the people of God, by Christ, from sin and Satan, and the world, law, hell, and death, as of the preservation and continuance of the Gospel church state, notwithstanding all the opposition and persecution of the Jews and Gentiles; and especially of the deliverance of the Lord's people, in the latter day, from the cruelty, captivity, and bondage of antichrist, by the destruction of him; which will occasion joy and praise, Revelation 18:4;

and will build the cities of Judah: erect Gospel churches in the Roman empire, and in the several parts of the world; as were in the first times of the Gospel, and will be in the latter day, when the cities of God shall be yet spread abroad through prosperity, Zechariah 1:17; of which the saints are citizens, and enjoy in them many privileges and immunities: these may be said to be "built", when they are built upon Christ, and on their most holy faith; when the members of them are edified and multiplied; when purity of faith, discipline, and worship, prevails among them; and though this is usually by the ministers of the Gospel, as instruments, yet the Lord is the chief builder; for, unless he builds, in vain do the builders build, Psalm 127:1;

that they may dwell there, and have it in possession; the men of Judah, such as confess the name of Christ, as the word "Judah" signifies; who profess to believe in him with their hearts; these have a name and a place, and an inheritance in the churches, and an abiding one; they shall never go out, but dwell in the house of God for ever; Gospel churches being erected and built up for their sakes, and for such ends and purposes.

For God will save Zion, and will build the cities of Judah: that they may dwell there, and have it in possession.

69:35 Sion - His church and people. They - His servants, as is explained in the following verse . There - In the literal Canaan for a long time, in the heavenly Canaan for ever.

69:30-36 The psalmist concludes the psalm with holy joy and praise, which he began with complaints of his grief. It is a great comfort to us, that humble and thankful praises are more pleasing to God than the most costly, pompous sacrifices. The humble shall look to him, and be glad; those that seek him through Christ shall live and be comforted. God will do great things for the gospel church, in which let all who wish well to it rejoice. A seed shall serve him on earth, and his servants shall inherit his heavenly kingdom. Those that love his name shall dwell before him for ever. He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? Arise, thou great Restorer of the ancient places to dwell in, and turn away ungodliness from thy people.
