In these three chapters, we see how Aaron was ordained as the High Priest and how his sons were ordained to be priests of the Lord. We see that the Lord has specific details about the process. They had to present a sin offering, burnt offering, an ordination offering which was when Moses put some blood on the priests right ear lobe, right thumb, and the big toe of their right foot. From their head to their toes, they were dedicated to the Lord. They also gave a fellowship offering and a meal offering. For seven days the Lord commanded they stay at the entrance to the tabernacle, and on that 8th day they had to present more sacrifices because the Lord was going to present Himself to them, and they would see His glory. Fire came from the presence of the Lord and consumed the burnt offering. The people rejoiced. Then we learn that two of Aaron's sons, Nadab and Abihu did their own thing in presenting fire before the Lord. They did not follow the Lord's directions, and fire once again came from the presence of the Lord and this time the fire consumed the two priests. It served as a reminder that those who serve theĀ Lord are to remember that God is holy, and we are to obey His direction. There are more details in last year's lesson which is called, "The Ordination of Aaron and Sons, and a Call to Holiness and Obedience," which was presented Jan. 31, 2023.
