31 “Take the ram for the ordination and cook the meat in a sacred place. 32 At the entrance to the tent of meeting, Aaron and his sons are to eat the meat of the ram and the bread that is in the basket. 33 They are to eat these offerings by which atonement was made for their ordination and consecration. But no one else may eat them, because they are sacred. 34 And if any of the meat of the ordination ram or any bread is left over till morning, burn it up. It must not be eaten, because it is sacred.
35 “Do for Aaron and his sons everything I have commanded you, taking seven days to ordain them. 36 Sacrifice a bull each day as a sin offering to make atonement. Purify the altar by making atonement for it, and anoint it to consecrate it. 37 For seven days make atonement for the altar and consecrate it. Then the altar will be most holy, and whatever touches it will be holy.
38 “This is what you are to offer on the altar regularly each day: two lambs a year old. 39 Offer one in the morning and the other at twilight. 40 With the first lamb offer a tenth of an ephah of the finest flour mixed with a quarter of a hin of oil from pressed olives, and a quarter of a hin of wine as a drink offering. 41 Sacrifice the other lamb at twilight with the same grain offering and its drink offering as in the morning—a pleasing aroma, a food offering presented to the Lord.
42 “For the generations to come this burnt offering is to be made regularly at the entrance to the tent of meeting, before the Lord. There I will meet you and speak to you; 43 there also I will meet with the Israelites, and the place will be consecrated by my glory.
44 “So I will consecrate the tent of meeting and the altar and will consecrate Aaron and his sons to serve me as priests. 45 Then I will dwell among the Israelites and be their God. 46 They will know that I am the Lord their God, who brought them out of Egypt so that I might dwell among them. I am the Lord their God. Exodus 29:31-46
Recall when Moses went up on the mountain, the Lord told him to take off his sandals for it was holy ground. In the same light, the Lord also consecrated the altar and made it holy. We don’t tend to view objects as holy but evidently the Lord did.
Again, the directions for Aaron and his sons were explicit and detailed, plus they (and only they) were able to eat some of the meat that they cooked on the altar. The rest would be burned.
Every day these men would be sacrificing lambs and other offerings.
It was their duty to offer this up on the consecrated altar twice a day.
They were doing it on behalf of the million or more people that escaped Egypt through the Red Sea. But the Lord would meet with them and speak to them. It could get old for them but it was probably exciting each day knowing they’d get to speak with the Lord God Himself.
For He was the Lord their God.
Just as He is the Lord our God.
