The psalmist here, both as a type of Christ and as an example to Christians, concludes a psalm with holy joy and praise which he began with complaints and remonstrances of his griefs.

I.He resolves to praise God himself, not doubting but that therein he should be accepted of him (Psa 69:30, Psa 69:31): "I will praise the name of God, not only with my heart, but with my song, and magnify him with thanksgiving;" for he is pleased to reckon himself magnified by the thankful praises of his people. It is intimated that all Christians ought to glorify God with their praises, in psalms, and hymns, and spiritual songs. And this shall please the Lord, through Christ the Mediator of our praises as well as of our prayers, better than the most valuable of the legal sacrifices (Psa 69:31), an ox or bullock. This is a plain intimation that in the days of the Messiah an end should be put, not only to the sacrifices of atonement, but to those of praise and acknowledgment which were instituted by the ceremonial law; and, instead of them, spiritual sacrifices of praise and thanksgiving are accepted - the calves of our lips, not the calves of the stall, Heb 13:15. It is a great comfort to us that humble and thankful praises are more pleasing to God than the most costly pompous sacrifices are or ever were.

II.He encourages other good people to rejoice in God and continue seeking him (Psa 69:32, Psa 69:33): The humble shall see this and be glad. They shall observe, to their comfort, 1. The experiences of the saints. They shall see how ready God is to hear the poor when they cry to him, and to give them that which they call upon him for, how far he is from despising his prisoners; though men despise them, he favours them with his gracious visits and will find a time to enlarge them. The humble shall see this and be glad, not only because when one member is honoured all the members rejoice with it, but because it is an encouragement to them in their straits and difficulties to trust in God. It shall revive the hearts of those who seek God to see more seals and subscriptions to this truth, that Jacob's God never said to Jacob's seed, Seek you me in vain. 2. The exaltation of the Saviour, for of him the psalmist had been speaking, and of himself as a type of him. When his sorrows are over, and he enters into the joy that was set before him, when he is heard and discharged from his imprisonment in the grave, the humble shall look upon it and be glad, and those that seek God through Christ shall live and be comforted, concluding that, if they suffer with him, they shall also reign with him.

III.He calls upon all the creatures to praise God, the heaven, and earth, and sea, and the inhabitants of each, Psa 69:34. Heaven and earth, and the hosts of both, were made by him, and therefore let heaven and earth praise him. Angels in heaven, and saints on earth, may each of them in their respective habitations furnish themselves with matter enough for constant praise. Let the fishes of the sea, though mute to a proverb, praise the Lord, for the sea is his, and he made it. The praises of the world must be offered for God's favours to his church, Psa 69:35, Psa 69:36. For God will save Zion, the holy mountain, where his service was kept up. He will save all that are sanctified and set apart to him, all that employ themselves in his worship, and all those over whom Christ reigns; for he was King upon the holy hill of Zion. He has mercy in store for the cities of Judah, of which tribe Christ was. God will do great things for the gospel church, in which let all that wish well to it rejoice. For, 1. It shall be peopled and inhabited. There shall be added to it such as shall be saved. The cities of Judah shall be built, particular churches shall be formed and incorporated according to the gospel model, that there may be a remnant to dwell there and to have it in possession, to enjoy the privileges conferred upon it and to pay the tributes and services required from it. Those that love his name, that have a kindness for religion in general, shall embrace the Christian religion, and take their place in the Christian church; they shall dwell therein, as citizens, and of the household of God 2. It shall be perpetuated and inherited. Christianity was not to be res unius aetatis - a transitory thin. No: The seed of his servants shall inherit it. God will secure and raise up for himself a seed to serve him, and they shall inherit the privileges of their fathers; for the promise is to you and your children, as it was of old. I will be a God to thee, and thy seed after thee. The land of promise shall never be lost for want of heirs, for God can out of stones raise up children unto Abraham and will do so rather than the entail shall be cut off. David shall never want a man to stand before him. The Redeemer shall see his seed, and prolong his days in them, till the mystery of God shall be finished and the mystical body completed. And since the holy seed is the substance of the world, and if that were all gathered in the world would be at an end quickly, it is just that for this assurance of the preservation of it heaven and earth should praise him.

For the Lord heareth the poor,.... The prayer of the poor, as the Targum; of the poor disciples of Christ, who were together mourning, weeping, and praying, when their Lord was dead, and laid in the sepulchre, Mar 16:10; this epithet agrees with all the followers of Christ, who for the most part are literally poor, and are all of them so in a spiritual sense; they are poor in spirit, and are sensible of it; they are full of wants, and these daily return upon them; wherefore they constantly apply to the throne of grace for help in time of need; and the Lord regards them, his eye is upon them, his heart is towards them, his thoughts are about them, his ears are open to their cries, and his hand is ready to supply their wants;

and despiseth not his prisoners; the same disciples of Christ; who being assembled together, the doors were shut for fear of the Jews, Joh 20:19; it may be applied to such who are the Lord's prisoners; that is, for his sake, in a literal sense, as the Apostle Paul is called the prisoner of the Lord, Eph 3:1; and there were many, both under the Old and under the New Testament, that suffered imprisonment for their profession of religion; and these the Lord despises not, though men may, but highly esteems and honours; and it may be understood mystically and spiritually of such as are, in their nature state, prisoner of sin and Satan, and the law, and, when called, are prisoners of hope; these the Lord has a regard unto, and opens the prison doors and sets them at and directs them to the strong hold, Isa 49:9.

prisoners--peculiarly liable to be despised.
