6 In sacrifice and offering you have not delighted, but you have given me an open ear.[1] Burnt offering and sin offering you have not required. 7 Then I said, "Behold, I have come; in the scroll of the book it is written of me: 8 I delight to do your will, O my God; your law is within my heart." 9 I have told the glad news of deliverance[2] in the great congregation; behold, I have not restrained my lips, as you know, O Lord. 10 I have not hidden your deliverance within my heart; I have spoken of your faithfulness and your salvation; I have not concealed your steadfast love and your faithfulness from the great congregation.

11 As for you, O Lord, you will not restrain your mercy from me; your steadfast love and your faithfulness will ever preserve me! 12 For evils have encompassed me beyond number; my iniquities have overtaken me, and I cannot see; they are more than the hairs of my head; my heart fails me. 13 Be pleased, O Lord, to deliver me! O Lord, make haste to help me! 14 Let those be put to shame and disappointed altogether who seek to snatch away my life; let those be turned back and brought to dishonor who delight in my hurt! 15 Let those be appalled because of their shame who say to me, "Aha, Aha!" 16 But may all who seek you rejoice and be glad in you; may those who love your salvation say continually, "Great is the Lord!" 17 As for me, I am poor and needy, but the Lord takes thought for me. You are my help and my deliverer; do not delay, O my God!

Matthew Henry's Commentary on Psalm 40:6-17

Commentary on Psalm 40:6-10

(Read Psalm 40:6-10)

The psalmist foretells that work of wonder, redemption by our Lord Jesus Christ. The Substance must come, which is Christ, who must bring that glory to God, and that grace to man, which it was impossible the sacrifices should ever do. Observe the setting apart of our Lord Jesus to the work and office of Mediator. In the volume, or roll, of the book it was written of him. In the close rolls of the Divine decrees and counsel, the covenant of redemption was recorded. Also, in all the volumes of the Old Testament something was written of him, John 19:28. Now the purchase of our salvation is made, the proclamation is sent forth, calling us to come and accept it. It was preached freely and openly. Whoever undertook to preach the gospel of Christ, would be under great temptation to conceal it; but Christ, and those he calls to that work, are carried on in it. May we believe his testimony, trust his promise, and submit to his authority.

Commentary on Psalm 40:11-17

(Read Psalm 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.
