10 “Bring the bull to the front of the tent of meeting, and Aaron and his sons shall lay their hands on its head. 11 Slaughter it in the Lord’s presence at the entrance to the tent of meeting. 12 Take some of the bull’s blood and put it on the horns of the altar with your finger, and pour out the rest of it at the base of the altar. 13 Then take all the fat on the internal organs, the long lobe of the liver, and both kidneys with the fat on them, and burn them on the altar. 14 But burn the bull’s flesh and its hide and its intestines outside the camp. It is a sin offering.
15 “Take one of the rams, and Aaron and his sons shall lay their hands on its head. 16 Slaughter it and take the blood and splash it against the sides of the altar. 17 Cut the ram into pieces and wash the internal organs and the legs, putting them with the head and the other pieces. 18 Then burn the entire ram on the altar. It is a burnt offering to the Lord, a pleasing aroma, a food offering presented to the Lord.
19 “Take the other ram, and Aaron and his sons shall lay their hands on its head. 20 Slaughter it, take some of its blood and put it on the lobes of the right ears of Aaron and his sons, on the thumbs of their right hands, and on the big toes of their right feet. Then splash blood against the sides of the altar. 21 And take some blood from the altar and some of the anointing oil and sprinkle it on Aaron and his garments and on his sons and their garments. Then he and his sons and their garments will be consecrated.
22 “Take from this ram the fat, the fat tail, the fat on the internal organs, the long lobe of the liver, both kidneys with the fat on them, and the right thigh. (This is the ram for the ordination.) 23 From the basket of bread made without yeast, which is before the Lord, take one round loaf, one thick loaf with olive oil mixed in, and one thin loaf. 24 Put all these in the hands of Aaron and his sons and have them wave them before the Lord as a wave offering. 25 Then take them from their hands and burn them on the altar along with the burnt offering for a pleasing aroma to the Lord, a food offering presented to the Lord. 26 After you take the breast of the ram for Aaron’s ordination, wave it before the Lord as a wave offering, and it will be your share.
27 “Consecrate those parts of the ordination ram that belong to Aaron and his sons: the breast that was waved and the thigh that was presented. 28 This is always to be the perpetual share from the Israelites for Aaron and his sons. It is the contribution the Israelites are to make to the Lord from their fellowship offerings.
29 “Aaron’s sacred garments will belong to his descendants so that they can be anointed and ordained in them. 30 The son who succeeds him as priest and comes to the tent of meeting to minister in the Holy Place is to wear them seven days. Exodus 29:10-30
Sacrificing animals was an extremely messy process. Because we get our meats from a grocery store or a butcher, we rarely have to deal with the mess of killing and cutting up animals.
The Hebrews, though, were accustomed to it because they had to do it just to eat.
The Lord gave Moses very narrow restrictions on how Aaron and his sons were to sacrifice animals to the Lord. They had to take great care to do it right lest it anger the Lord.
It wasn’t that the Lord would get offended by something like this. No, the Lord gave Aaron and his sons simple and detailed directions on something that only they were permitted to do. He entrusted them to obey those directions.
In an age of supercomputing, millions of calculations can be processed in a very short period of time. Chain a few of the super computers together, and the number of calculations are astronomical.
I don’t know this to be fact, but the Father and Son ran through all possible calculations that ever could have been made (probably in a split section), and there was only one solution to the problem of humanity: God the Son would have to put on human flesh and be the Sacrificial Lamb.
There was no other way.
We should be very thankful for the messiness Christ went through on our behalf. It was the only way to redeem lost humanity.
Yesterday He loved me,
Today He’ll do the same.
How long can it last?
Forever, praise His name. – Warren W. Wiersbe
