Exodus 29:21

21 And thou shalt take of the blood from the altar, and of the anointing oil; and thou shalt sprinkle it upon Aaron and on his garments, and on his sons and on his sons' garments with him; and he shall be sanctified and his apparel, and his sons and his sons' apparel with him: but the blood of the ram thou shalt pour round about upon the altar.

Exodus 29:21 Meaning and Commentary

Exodus 29:21

And thou shalt take of the blood that is upon the altar
Not that which was sprinkled upon it, which could not be gathered up in such quantities as to be sprinkled again; but which was in a basin on it, having been received into it when the ram was slain:

and of the anointing oil;
hereafter to be made, and with which Aaron was anointed as soon as he had his garments on; and this is a different anointing from that that was poured on his head; this was sprinkled on his garments, as follows:

and sprinkle it upon Aaron;
both the blood and the oil:

and upon his garments;
the note of Aben Ezra is, under the garments of Aaron, and on his garments, as if they were sprinkled within and without:

and upon his sons, and upon the garments of his sons with him;
at his first unction his sons do not seem to have been anointed at all, but now they and their garments are sprinkled both with blood and oil; denoting both the justification of the priests of the Lord by the blood of Christ, and the sanctification of them by the Spirit, and the need that both their persons and their actions stand in of cleansing by them both:

and he shall be hallowed, and his garments, and his sons, and his sons'
garments with him:
all should be holy in a ceremonial sense, and devoted to holy uses and services; see ( Psalms 45:8 ) ( Revelation 7:14 ) .

Exodus 29:21 In-Context

19 And thou shalt take the second ram, and Aaron and his sons shall lay their hands on the head of the ram.

20 And thou shalt kill it, and take of the blood of it, and put it on the tip of Aaron's right ear, and on the thumb of his right hand, and on the great toe of his right foot, and on the tips of the right ears of his sons, and on the thumbs of their right hands, and on the great toes of their right feet.

21 And thou shalt take of the blood from the altar, and of the anointing oil; and thou shalt sprinkle it upon Aaron and on his garments, and on his sons and on his sons' garments with him; and he shall be sanctified and his apparel, and his sons and his sons' apparel with him: but the blood of the ram thou shalt pour round about upon the altar.

22 And thou shalt take from the ram its fat, both the fat that covers the belly, and the lobe of the liver, and the two kidneys, and the fat that is upon them, and the right shoulder, for this is a consecration.

23 And one cake with oil, and one cake from the basket of unleavened bread set forth before the Lord.
