And Aaron lifted up his hand toward the people, and blessed them, and {h} came down from offering of the sin offering, and the burnt offering, and peace offerings.

(h) Because the altar was near the sanctuary, which was the upper end, therefore he is said to come down.

Wesley's Notes

9:22 Aaron lifted up his hands - Which was the usual rite of blessing. By this posture he signified both whence he expected the blessing, and his hearty desire of it for them. And blessed them - In some such manner, as is related, Num 6:24, and c. though not in the same form, for it is not probable that he used it before God delivered it And this blessing was an act of his priestly office, no less than sacrificing. And herein be was a type of Christ, who came into the world to bless us, and when he was parting from his disciples, lifted up his hands and blessed them: yea, and in them his whole church, of which they were the elders and representatives. And came down - From the altar; whence he is said to come down, either Because the altar stood upon raised ground, or Because it was nearer the holy place, which was the upper end.

Jamieson-Fausset-Brown Bible Commentary

22. Aaron lifted up his hand . and blessed them-The pronouncing of a benediction on the people assembled in the court was a necessary part of the high priest's duty, and the formula in which it was to be given is described (Nu 6:23-27).

came down from offering-The altar was elevated above the level of the floor, and the ascent was by a gentle slope (Ex 20:26).

Matthew Henry's Concise Commentary

9:22-24 When the solemnity was finished, and the blessing pronounced, God testified his acceptance. There came a fire out from before the Lord, and consumed the sacrifice. This fire might justly have fastened upon the people, and have consumed them for their sins; but its consuming the sacrifice signified God's acceptance of it, as an atonement for the sinner. This also was a figure of good things to come. The Spirit descended upon the apostles in fire. And the descent of this holy fire into our souls, to kindle in them pious and devout affections toward God, and such a holy zeal as burns up the flesh and the lusts of it, is a certain token of God's gracious acceptance of our persons and performances. Nothing goes to God, but what comes from him. We must have grace, that holy fire, from the God of grace, else we cannot serve him acceptably, Heb 12:28. The people were affected with this discovery of God's glory and grace. They received it with the highest joy; triumphing in the assurance given them that they had God nigh unto them. And with the lowest reverence; humbly adoring the majesty of that God, who vouchsafed thus to manifest himself to them. That is a sinful fear of God, which drives us from him; a gracious fear makes us bow before him.

Matthew Henry's Whole Bible Commentary

Verses 8-22

These being the first offerings that ever were offered by the levitical priesthood, according to the newly-enacted law of sacrifices, the manner of offering them is particularly related, that it might appear how exactly they agreed with the institution. 1. Aaron with his own hands slew the offering (v. 8), and did the work of the inferior priests; for, great as he was, he must not think any service below him which he could do for the honour of God: and, as Moses had shown him how to do this work decently and dexterously, so he showed his sons, that they might do likewise; for this is the best way of teaching, and thus parents should instruct their children by example. Therefore as Moses before, so Aaron now offered some of each of the several sorts of sacrifices that were appointed, whose rites differed, that they might be thoroughly furnished for every good work. 2. He offered these besides the burnt-sacrifice of the morning, which was every day offered first, v. 17. Note, Our accustomed devotions morning and evening, alone and in our families, must not be omitted upon any pretence whatsoever, no, not when extraordinary services are to be performed; whatever is added, these must not be diminished. 3. It is not clear whether, when it is said that he burnt such and such parts of the sacrifices upon the altar (v. 10-20), the meaning is that he burnt them immediately with ordinary fire, as formerly, or that he laid them upon the altar ready to be burnt with the fire from heaven which they expected (v. 24), or whether, as bishop Patrick thinks, he burnt the offerings for himself with ordinary fire, but when they were burnt out he laid the people's sacrifices upon the altar, which were kindled and consumed by the fire of the Lord. I would rather conjecture, because it is said of all these sacrifices that he burnt them (except the burnt-offering for the people, of which it is said that he offered it according to the manner, v. 16, which seems to be equivalent), that he did not kindle the fire to burn them, but that then the fire from the Lord fastened upon them, put out the fire that he had kindled (as we know a greater fire puts out a less), and suddenly consumed the remainder, which the fire he had kindled would have consumed slowly. 4. When Aaron had done all that on his part was to be done about the sacrifices he lifted up his hand towards the people, and blessed them, v. 22. This was one part of the priest's work, in which he was a type of Christ, who came into the world to bless us, and when he was parted from his disciples, at his ascension, lifted up his hands and blessed them, and in them his whole church, of which they were the elders and representatives, as the great high priest of our profession. Aaron lifted up his hands in blessing them, to intimate whence he desired and expected the blessing to come, even from heaven, which is God's throne. Aaron could but crave a blessing, it is God's prerogative to command it. Aaron, when he had blessed, came down; Christ, when he blessed, went up.
