John Gill's Exposition of the Whole Bible
Psalms 35:27
Let them shout for joy, and be glad, that favour my righteous cause,.... The cause of David was a righteous cause, he having done no iniquity, or anything criminal against Saul his enemy, who persecuted him; and there were some that favoured his cause, as Jonathan, Saul's son, and a few others of rank and figure; but the greatest part were mean and despicable, 1 Samuel 22:2; and so the cause of Christ and of his people, which is one, is a righteous cause, which no one need to be ashamed of, and is worth suffering for; though those that favour it are for the most part the poor and base and weak things of the world: but when this cause prospers they rejoice and are glad, as they do at the happiness of every particular saint; for if one member is honoured, all the rest rejoice with it;
yea, let them say continually, the Lord be magnified; let them continually ascribe greatness, give honour and glory, to him,
which hath pleasure in the prosperity of his servant; meaning either himself, who was a servant of the Lord, not only by creation, but by grace; and who had his times both of temporal and spiritual prosperity; which were owing to the good will and pleasure of God, and to the delight and complacency he had in him, being a man after his own heart, raised up to fulfil his will; and since this prosperity did not arise from any desert of his, he would have all the glory of it given to God: or else he intends the Messiah, his antitype, who, as Mediator, is the servant of the Lord; of his choosing, calling, and sending; whose commands he diligently and faithfully obeyed; from whom he had his work, and also his reward: his prosperity lies in the work of redemption succeeding in his hands; in his exaltation at the right hand of God; and in the spread of his Gospel in the world, and the efficacy of it to the conviction of sinners; and in the establishment and increase of his kingdom and interest; on which account the Lord's name is to be magnified and glorified, who delights in him as his servant, and in his prosperity; and the rather this is to be done, since the saints have an interest in him as a Prince and a Saviour: or anyone of the servants of the Lord may be understood; or however it is applicable to anyone of them, who, through the power of divine grace upon them, are made willing to serve the Lord with reverence and godly fear; who are his Hephzibah, in whom is all his delight and pleasure, Isaiah 62:4; who rejoices over them to do them good: and hence flows all the spiritual prosperity they enjoy, on account of which glory is to be given to God by them and all the saints that know it, Psalms 34:1.
