Exodus 29:1  “…do to them to hallow them for ministering…”
To set them apart to be priests.  I figure they’ll repeat this for each set of men who become priests.  Will probably find more on this in Leviticus.

1  “…without blemish”
Always important.  What is to represent God and His dealings was to be without spot or blemish, to be perfect.

2  “…unleavened bread, unleavened cakes mixed with oil, and unleavened wafers…”
Same way with things being unleavened, without sin.

9  “…priesthood shall be theirs for a perpetual statute…”
Priesthood belongs to Aaron and his descendants.  Interesting that Christ didn’t come out of the Levitic, Aaronic line.

10  “…shall put their hands on the head of the bull”
Symbolically transferring the sin to the animal, or having the animal represent them to accept the punishment for their sin.

12  “You shall take some of the blood of the bull and put it on the horns of the altar with your finger…”
Marking of blood to show the payment for sin and as a sign of the covenant.

18  “…you shall burn the whole ram on the altar. It is a burnt offering to the LORD…”
Doing this is what would be called a whole burnt offering.  It’s what most people think of when they hear sacrifice.  But all offerings and sacrifices aren’t whole burnt ones.

20-21  “…take some of its blood and put it on the tip of the right ear of Aaron and on the tip of the right ear of his sons, on the thumb of their right hand and on the big toe of their right foot, and sprinkle the blood all around on the altar…take some of the blood that is on the altar, and some of the anointing oil, and sprinkle it on Aaron and on his garments, on his sons and on the garments of his sons with him…”
Marked with the blood of the sacrifice as well as that on the altar.  They’ve now been purified by blood connected with the sacrifice and that of the altar which provides a way to be cleansed.  One commentary suggested the anointing with the oil brought in the idea of the Spirit.  It’s a possibility, but I’m not sure how you prove it.  Symbolism exists, but sometimes that leaves the door open to different interpretations.

24  “…you shall wave them as a wave offering…”
Priest would wave the item in the air to show it was offered to the LORD.  One commentary suggested this was different from a heave offering in that the wave was done several times while the heave only once, presented as it were.

27  “…which is for Aaron and of that which is for his sons”
Some of the offerings were waved before the LORD to show their presentation, but then were given to the priests to consume.  This provided meals to the priests of God by the offerings made to Him.

29  “…holy garments of Aaron shall be his sons’ after him, to be anointed in them and to be consecrated in them”
Passing down of the High Priest garments.  May have answered my earlier question of succession.  Commentary agrees.  The son who would be the new High Priest would be anointed and consecrated in the garments upon taking the office.

33  “They shall eat those things with which the atonement was made, to consecrate and to sanctify them; but an outsider shall not eat them, because they are holy.”
Only the priests were allowed to eat the showbread of the tabernacle.  However, David would one day go in and eat of it because he and his men needed something to eat.  Christ used that example to show that the tabernacle was made for man, not the other way around.

37  “…the altar shall be most holy…”
As the instrument which provided atonement.  It was consecrated and anything that touched it had to be consecrated.

38  “…two lambs of the first year, day by day continually”
Daily offerings.  One in the morning and one in the evening, along with flour, oil, and wine.  Burned upon the altar.

45  “I will dwell among the children of Israel and will be their God.”
That was the idea.  Not sure where it’s recorded, will probably come across it soon, but the tribes were to be laid out on the compass points, three to the north and south and three to the east and west with the tabernacle in the center.  God would be there, in the midst of His people.

46  “…they shall know that I am the LORD their God…”
How neat that would be.  The tribes all laid out with the visible presence of God in their midst all the time.  All they had to do was step out of their tents and look toward the tabernacle to see Him.  Their God visibly with them all the time.  God’s plan was wonderful.

I hope you enjoy reading and studying His word.  May it accomplish what He desires.  Please feel free to comment or post questions.  Thanks for reading!
