Exodus 40:31 describes Moses, Aaron, and his sons washing their hands and feet at a basin before they entered the tabernacle or approached the altar. The verse shows priests preparing themselves physically and ceremonially before they served God in his dwelling place. It comes from the book of Exodus, which Jewish and Christian tradition associates with Moses, and it is addressed to the Israelite community as a record of how the sanctuary was finally set up.

What Exodus 40:31 Means
The verse names three people: Moses, who led Israel and received God’s instructions; Aaron, his brother, who would serve as the first high priest; and Aaron’s sons, who would assist him. All three wash, which tells you the cleansing was not reserved for one leader. Everyone involved in the sacred work needed to be made ready.
The washing is specific. Hands and feet were the parts of the body used for lifting, carrying, handling sacrifices, and walking into holy space. Cleaning them was a visible sign that the people approaching God were setting aside the ordinary grime of daily life. The verse does not explain every detail of the ritual, but it clearly shows that worship in God’s presence had an order and a seriousness to it.
What the verse does not promise is that washing hands makes anyone righteous on its own. The water marked a separation between common and holy things. Later Scripture makes clear that God looks at the heart, so the ritual pointed beyond itself to a real need for inner cleansing.
The Context of Exodus 40:31
Exodus 40 closes the long account of how Israel built the tabernacle, the portable sanctuary God commanded in the wilderness after the rescue from Egypt. The surrounding verses describe Moses setting up the screen at the entrance, placing the altar of burnt offering, and positioning a basin filled with water between the tent and the altar. Verse 31 comes right after the basin is set in place, so the washing is the first use of that furniture. The chapter then ends with the cloud covering the tent and the Lord’s glory filling it in verse 34.
Seeing the verse at the end of the building account changes how it reads. The washing is not a random detail. It is the point at which the sanctuary is ready for use, and the cleansing comes just before God shows his presence there. The order of events teaches that approaching God in his dwelling requires preparation, and that his glory fills a space made ready for him.
