3 Then I set my face toward the Lord God to make request by prayer and supplications, with fasting, sackcloth, and ashes.

4 And I prayed to the Lord my God, and made confession, and said, "O Lord, great and awesome God, who keeps His covenant and mercy with those who love Him, and with those who keep His commandments, 5 we have sinned and committed iniquity, we have done wickedly and rebelled, even by departing from Your precepts and Your judgments. 6 Neither have we heeded Your servants the prophets, who spoke in Your name to our kings and our princes, to our fathers and all the people of the land. 7 O Lord, righteousness belongs to You, but to us shame of face, as it is this day--to the men of Judah, to the inhabitants of Jerusalem and all Israel, those near and those far off in all the countries to which You have driven them, because of the unfaithfulness which they have committed against You. 8 O Lord, to us belongs shame of face, to our kings, our princes, and our fathers, because we have sinned against You. 9 To the Lord our God belong mercy and forgiveness, though we have rebelled against Him. 10 We have not obeyed the voice of the Lord our God, to walk in His laws, which He set before us by His servants the prophets. 11 Yes, all Israel has transgressed Your law, and has departed so as not to obey Your voice; therefore the curse and the oath written in the Law of Moses the servant of God have been poured out on us, because we have sinned against Him. 12 And He has confirmed His words, which He spoke against us and against our judges who judged us, by bringing upon us a great disaster; for under the whole heaven such has never been done as what has been done to Jerusalem.

Matthew Henry's Commentary on Daniel 9:3-12

Commentary on Daniel 9:1-3

(Read Daniel 9:1-3)

Daniel learned from the books of the prophets, especially from Jeremiah, that the desolation of Jerusalem would continue seventy years, which were drawing to a close. God's promises are to encourage our prayers, not to make them needless; and when we see the performance of them approaching, we should more earnestly plead them with God.

Commentary on Daniel 9:4-19

(Read Daniel 9:4-19)

In every prayer we must make confession, not only of the sins we have been guilty of, but of our faith in God, and dependence upon him, our sorrow for sin, and our resolutions against it. It must be our confession, the language of our convictions. Here is Daniel's humble, serious, devout address to God; in which he gives glory to him as a God to be feared, and as a God to be trusted. We should, in prayer, look both at God's greatness and his goodness, his majesty and mercy. Here is a penitent confession of sin, the cause of the troubles the people for so many years groaned under. All who would find mercy must thus confess their sins. Here is a self-abasing acknowledgment of the righteousness of God; and it is evermore the way of true penitents thus to justify God. Afflictions are sent to bring men to turn from their sins, and to understand God's truth. Here is a believing appeal to the mercy of God. It is a comfort that God has been always ready to pardon sin. It is encouraging to recollect that mercies belong to God, as it is convincing and humbling to recollect that righteousness belongs to him. There are abundant mercies in God, not only forgiveness, but forgivenesses. Here are pleaded the reproach God's people was under, and the ruins God's sanctuary was in. Sin is a reproach to any people, especially to God's people. The desolations of the sanctuary are grief to all the saints. Here is an earnest request to God to restore the poor captive Jews to their former enjoyments. O Lord, hearken and do. Not hearken and speak only, but hearken and do; do that for us which none else can do; and defer not. Here are several pleas and arguments to enforce the petitions. Do it for the Lord Christ's sake; Christ is the Lord of all. And for his sake God causes his face to shine upon sinners when they repent, and turn to him. In all our prayers this must be our plea, we must make mention of his righteousness, even of his only. The humble, fervent, believing earnestness of this prayer should ever be followed by us.
