Moses & Aaron's role in Exodus 40:31?
What role did Moses and Aaron play in the cleansing process in Exodus 40:31?

Scripture Focus

“From it Moses and Aaron and his sons washed their hands and feet.” (Exodus 40:31)


Setting the Scene

• The Tabernacle has just been erected (Exodus 40:17).

• A bronze basin filled with water now sits “between the Tent of Meeting and the altar” (40:30).

• God has already commanded that priests must wash “so that they will not die” when they come near His presence (Exodus 30:17-21).


What Moses Did

• Personally obeyed the command—he washed alongside the priests.

• Modeled the standard: even the leader who spoke with God face-to-face needed cleansing (Numbers 12:7-8).

• Functioned as the covenant mediator, ensuring every step of God’s instructions was carried out “just as the LORD had commanded” (Exodus 40:32).

• Consecrated the priests; his participation validated the ceremonial process (Exodus 29:4, 40:12-13).


What Aaron (and His Sons) Did

• Submitted to the ritual to qualify for ministry at altar and Tent of Meeting.

• Entered God’s service only after washing—highlighting that ministry starts with purity (Leviticus 8:6).

• Repeated the practice: verse 32 notes they washed every time they approached, turning a one-time consecration into a continual habit.


Why the Washing Matters

• Symbolized separation from sin and daily defilement (Psalm 24:3-4).

• Guarded life—failure to wash meant death (Exodus 30:21).

• Prepared hands and feet—the parts most active in service—to be clean for holy work.

• Foreshadowed the fuller cleansing “imposed until a time of reformation” (Hebrews 9:10).


Forward Glance to Christ

• Jesus echoes the basin when He washes the disciples’ feet (John 13:8-10), insisting cleansing is essential for fellowship.

• His blood provides the ultimate washing priests could only picture (Revelation 1:5-6).

• Believers are now called “a royal priesthood” who still pursue daily cleansing through confession (1 John 1:9).


Takeaway for Today

• No one is exempt from God’s standard—leadership begins with personal purity.

• Service flows out of cleansing; hands and feet readied for the tasks God assigns.

• Continual washing points us to continual dependence on the finished work of Christ, the greater Mediator.
