The glory of the Lord - Compare Exodus 16:7.

And the glory of the Lord shall appear - God shall give the most sensible signs of his presence among you; this he did in general by the cloud on the tabernacle, but in this case the particular proof was the fire that came out from before the Lord, and consumed the burnt-offering; see Leviticus 9:23, Leviticus 9:24.

This is the thing which the Lord commanded that ye should do,.... Namely, what they had done, bring the creatures and things for sacrifice they had:

and the glory of the Lord shall appear unto you; either Christ, the brightness of his Father's glory, in an human form, as a presage of his future incarnation, as he frequently did; or some more than ordinary refulgence of glory breaking out of the holy of holies, where God had now taken up his dwelling between the cherubim; or, as Aben Ezra explains it, the fire that should go out from him, and consume the sacrifice, which would be a demonstration of his presence with them, and of his acceptance of the sacrifice.

After everything had been prepared for the solemn ceremony, Moses made known to the assembled people what Jehovah had commanded them to do in order that His glory might appear (see at Exodus 16:10). Aaron was to offer the sacrifices that had been brought for the reconciliation of himself and the nation.

And Moses said, This is the thing which the LORD commanded that ye should do: and the glory of the LORD shall appear unto you.

9:6 The glory of the Lord - The glorious manifestation of God's powerful and gracious presence.

9:1-21 These many sacrifices, which were all done away by the death of Christ, teach us that our best services need washing in his blood, and that the guilt of our best sacrifices needs to be done away by one more pure and more noble than they. Let us be thankful that we have such a High Priest. The priests had not a day's respite from service allowed. God's spiritual priests have constant work, which the duty of every day requires; they that would give up their account with joy, must redeem time. The glory of God appeared in the sight of the people, and owned what they had done. We are not now to expect such appearances, but God draws nigh to those who draw nigh to him, and the offerings of faith are acceptable to him; though the sacrifices being spiritual, the tokens of the acceptance are spiritual likewise. When Aaron had done all that was to be done about the sacrifices, he lifted up his hands towards the people, and blessed them. Aaron could but crave a blessing, God alone can command it.
