Yea, whiles I was speaking in prayer, even the man Gabriel, whom I had seen in the vision at the beginning, being caused to fly swiftly, touched me about the time of the evening oblation.

Wesley's Notes

9:21 About the time - The time of the evening sacrifice was a solemn and set time of devotion. Tho' the altar was in ruins, and there was no oblation offered upon it, yet the pious Jews were daily thoughtful of the time when it should have been offered, and hoped that their prayer would be set forth before God as incense, and the lifting up of their hands, as the evening sacrifice. This was peculiarly a type of that great sacrifice, which Christ was to offer: and it was in virtue of that sacrifice, that Daniel's prayer was accepted, when he prayed for the Lord's sake.

King James Translators' Notes

swiftly: Heb. with weariness, or, flight

Jamieson-Fausset-Brown Bible Commentary

21. I had seen in the vision at the beginning-namely, in the former vision by the river Ulai (Da 8:1, 16).

fly swiftly-literally, "with weariness," that is, move swiftly as one breathless and wearied out with quick running [Gesenius]. English Version is better (Isa 6:2; Eze 1:6; Re 14:6).

time of . evening oblation-the ninth hour, three o'clock (compare 1Ki 18:36). As formerly, when the temple stood, this hour was devoted to sacrifices, so now to prayer. Daniel, during the whole captivity to the very last, with pious patriotism never forgot God's temple-worship, but speaks of its rites long abolished, as if still in use.

Matthew Henry's Concise Commentary

9:20-27 An answer was immediately sent to Daniel's prayer, and it is a very memorable one. We cannot now expect that God should send answers to our prayers by angels, but if we pray with fervency for that which God has promised, we may by faith take the promise as an immediate answer to the prayer; for He is faithful that has promised. Daniel had a far greater and more glorious redemption discovered to him, which God would work out for his church in the latter days. Those who would be acquainted with Christ and his grace, must be much in prayer. The evening offering was a type of the great sacrifice Christ was to offer in the evening of the world: in virtue of that sacrifice Daniel's prayer was accepted; and for the sake of that, this glorious discovery of redeeming love was made to him. We have, in verses 24-27, one of the most remarkable prophecies of Christ, of his coming and his salvation. It shows that the Jews are guilty of most obstinate unbelief, in expecting another Messiah, so long after the time expressly fixed for his coming. The seventy weeks mean a day for a year, or 490 years. About the end of this period a sacrifice would be offered, making full atonement for sin, and bringing in everlasting righteousness for the complete justification of every believer. Then the Jews, in the crucifixion of Jesus, would commit that crime by which the measure of their guilt would be filled up, and troubles would come upon their nation. All blessings bestowed on sinful man come through Christ's atoning sacrifice, who suffered once for sins, the just for the unjust, that he might bring us to God. Here is our way of access to the throne of grace, and of our entrance to heaven. This seals the sum of prophecy, and confirms the covenant with many; and while we rejoice in the blessings of salvation, we should remember what they cost the Redeemer. How can those escape who neglect so great salvation!
