Verse 16. - Let all those that seek thee rejoice and be glad in thee. The psalmist cannot long be satisfied with mere prayer for self. He must extend his supplication, and make it cover the whole body of the faithful, "all those that seek God" (comp. Psalm 25:2, 3, 20-22; Psalm 28:1-9, etc.). Let such as love thy salvation say continually, The Lord be magnified; ie. "Give them constant occasion to say, and give them the grateful heart to say, The Lord be praised for his mercies" (comp. Psalm 35:27).

40:11-17 The best saints see themselves undone, unless continually preserved by the grace of God. But see the frightful view the psalmist had of sin. This made the discovery of a Redeemer so welcome. In all his reflections upon each step of his life, he discovered something amiss. The sight and sense of our sins in their own colours, must distract us, if we have not at the same time some sight of a Saviour. If Christ has triumphed over our spiritual enemies, then we, through him, shall be more than conquerors. This may encourage all that seek God and love his salvation, to rejoice in him, and to praise him. No griefs nor poverty can render those miserable who fear the Lord. Their God, and all that he has or does, is the ground of their joy. The prayer of faith can unlock his fulness, which is adapted to all their wants. The promises are sure, the moment of fulfilment hastens forward. He who once came in great humility, shall come again in glorious majesty.Let all those that seek thee,.... In the first place, with their whole hearts, earnestly and diligently, in Christ, and under the influences of his Spirit, for pardon, righteousness, communion, larger measures of grace, and for honour, glory, immortality, and eternal life;

rejoice and be glad in thee: as their covenant God, the Father of their mercies, the God of all comfort and salvation, who pardons their sins, clothes them with the robes of righteousness and garments of salvation, and accepts their persons in Christ; all which is matter of joy and gladness: Christ is concerned for the joy of his people, John 15:11; the Targum is, "they shall", or "let them rejoice, and be glad in thy word": in himself, the essential Word, in whom there is always ground and reason of joy and gladness; because of his person, blood, righteousness, and sacrifice;

let such as love thy salvation; either Christ, who is God's salvation, Genesis 49:18; and who is loved by his people, universally, superlatively, and sincerely; or the salvation of him, his deliverance from the grave, resurrection from the dead, and exaltation; the benefits of which believers share in, and so have reason to love it: or the salvation he is the author of, which is loved by those that know it; partly because agreeable to the divine perfections, the glory of God is great in it; and partly because it is so full and complete in itself, and so suitable to them;

say continually, the Lord be magnified; let this be their constant employment in this world, as it will be for ever in the next, to ascribe greatness to God; or greatly to praise him, because of the great salvation wrought out for them.
