Meaning in one sentence
Why did God command washing before anointing? The cleansing and consecration of Aaron and his sons in Exodus 40:12, 15, and what it means for us.
Context
Exodus 40 is the final chapter of the book, where everything God commanded about the tabernacle comes together. Moses is told to set up the tent and anoint every piece of furniture, altar, basin, lampstand, each one made holy for God's presence. Then God gives instructions about the priests. Aaron and his sons are to be brought to the entrance of the Tent of Meeting. They must be washed with water, clothed in sacred garments, anointed with oil, and consecrated. This is their ordination. The passage repeats the pattern first given in Exodus 29, but now it is the moment of action. The tabernacle is ready. Now those who will serve in it must be made ready too.
Key Words
Three Hebrew verbs carry the weight of these verses. Wash (ra·chatz) is the ordinary word for bathing the body, but here it is not about hygiene, it is ritual cleansing. Before a person could stand before a holy God, every trace of ordinary dirt had to be removed. The same word is used in Leviticus for washing the burnt offering.
Anoint (ma·shach) means to smear or rub with oil. This is the word that gives us 'Messiah', the Anointed One. Aaron and his sons were marked out by oil as belonging to God. The oil was not just decoration; it set them apart for a specific work.
Consecrate (qa·dash) means to make holy, to separate. It is the same root as the word for 'holy' (qa·dosh). God does not simply ask the priests to behave better; He declares them set apart by His act. The washing, anointing, and consecration together form a single movement: God cleans, claims, and commissions His servants.
How Christians Read This Verse
Christian readers across traditions have seen this passage as pointing to something beyond the Old Testament. John Wesley wrote that the anointing was a seal the priesthood would continue as long as the Jewish polity lasted, until the Messiah came. Matthew Henry noted that the priests could not minister before they were anointed, showing that no one can serve God without a special call and cleansing.
Reformed commentators such as Calvin emphasized that the physical anointing ceased with Christ, the true High Priest. Roman Catholic and Orthodox traditions see a continuity: ordained ministry today is shaped by this pattern of setting apart with prayer and anointing, though they differ on how directly the Old Testament ritual applies. Both traditions agree that this passage speaks of God's initiative: He is the one who makes people holy for His service.
A common misunderstanding
Some readers think the washing and anointing were purely outward ceremonies with no inner meaning. In fact, the whole ritual showed that approaching God requires a real change of state. The water signified cleansing from impurity; the oil signified being claimed by God. These were not empty symbols but acts that carried the reality of God's work. The priests were not just 'pretending' to be clean; God was actually making them holy for His presence.
Living This Out
Before Aaron and his sons could serve, they needed to be washed. You cannot serve God on your own terms or in your own dirt. This week, before you teach, lead, or even help someone, pause and let God clean you. That might mean confessing an attitude you carried into the day. It might mean asking Him to set apart your ordinary morning for His purposes. The washing is not a punishment; it is the doorway to usefulness. You do not make yourself ready, He does. Your part is to come to the entrance and let Him do His work.
Main takeaway: God washes, clothes, and anoints His servants, making them holy by His own act so they can minister to Him.
For Families
For ages 5, 8
God told Moses to wash Aaron and his sons with water before they could help in the special tent. The washing meant they were clean enough to be near God.
For ages 9, 12
Before Aaron and his sons could serve as priests, God said they had to be washed, dressed in special clothes, and anointed with oil. This was not just a bath, it was a way of saying that only God can make a person holy enough to serve Him. It reminds us that we cannot make ourselves ready for God; He has to do it.
Questions People Ask
Why did God command water washing before anointing the priests?
The washing with water symbolized purification from impurity. Before anyone could approach a holy God in the tabernacle, they needed to be cleansed. It was a physical act that carried a spiritual meaning: God’s servants must be made clean by His provision, not by their own effort.
Was the anointing of Aaron’s sons the same as Aaron’s?
The text says to anoint them 'just as you anointed their father,' but other passages show a difference. Aaron, as high priest, had oil poured on his head (Exodus 29:7). His sons likely received anointing oil sprinkled on them and their garments (Exodus 29:21). Both were set apart, but the high priest received a fuller sign of consecration.
What does 'an everlasting priesthood' mean in verse 15?
The Hebrew word olam often means 'for a long duration' or 'for the age,' not necessarily 'forever without end.' In this context, the priesthood was established as a permanent institution for Israel, lasting as long as the covenant with Israel stood. Christians believe it pointed forward to Christ, the eternal High Priest.
Does this priestly anointing apply to Christian ministers today?
Christians differ on this. Some traditions see the ordained ministry as a continuation of the Old Testament priesthood, with anointing at ordination. Others see Christ as the only High Priest and all believers as a royal priesthood (1 Peter 2:9), so physical anointing is not required. Both agree that God sets apart people for service and grants them the holiness they need.
Why is this passage part of the tabernacle dedication?
The tabernacle was God’s dwelling place among Israel. Before worship could begin, every part, furniture, courtyard, priests, had to be consecrated. The priests were not separate from the place; they were part of the sacred space. Their washing and anointing completed the dedication, making the whole tabernacle ready for God’s glory to fill it.
