Exodus 40:10 tells Moses to pour sacred oil over the altar of burnt offering and its equipment, setting it apart for God’s exclusive use so that it becomes most holy. God speaks this instruction to Moses, who is leading the Israelites as they finish building the tabernacle in the wilderness. The verse is a command about preparing a place where the people could approach God through sacrifice.
You shall anoint the altar of burnt offering, with all its vessels, and sanctify the altar: and the altar will be most holy.
Exodus 40:10 (WEB)
What Exodus 40:10 Means
The phrase “anoint the altar” means pouring consecrating oil on the altar, a physical act that marked the object as belonging to God. In ancient Israel, anointing signaled that something had been chosen and set aside for a special purpose, much as kings and priests were anointed for their roles. The altar was not just a piece of furniture; anointing transferred it from ordinary use into the service of the Lord.
The words “with all its vessels” extend the consecration to every tool used with the altar, such as the pans, shovels, basins and forks used for handling sacrifices. Nothing connected to the altar’s work was left out. The phrase “sanctify the altar” means to make holy, and the closing statement that the altar “will be most holy” describes its status as set apart and not to be used for common purposes. The verse does not promise that the altar will do anything on its own; it describes a sacred setting apart for worship that God himself had ordained.
The Context of Exodus 40:10
Exodus is traditionally attributed to Moses and tells the story of Israel’s deliverance from Egypt, the giving of the law at Sinai, and the construction of the tabernacle, God’s dwelling place among his people. Chapter 40 is the final chapter of the book, and it records the setting up of the tabernacle and the installation of its furniture, following the detailed instructions given in earlier chapters. The original audience was the Israelite community in the wilderness, a people learning how to live in relationship with a holy God.
Just before verse 10, God commands that the tabernacle and its furniture be anointed, and just after, the basin and its base are to be anointed and sanctified, followed by the washing and anointing of Aaron and his sons as priests. Read in this sequence, the altar is one step in a careful process of preparing the whole sanctuary and its servants. The verse shows that holiness in Israel’s worship was ordered and deliberate, built piece by piece rather than assumed.

A Short Prayer From Exodus 40:10
Lord, you set apart the altar so that it could serve your holy purposes, and you ask me to belong to you in the same way. Show me the parts of my day that I have kept for myself, and help me to offer them to you with honest and willing hearts. Make my work, my words and my relationships into small acts of worship that honor your name. Teach me to live as someone set apart for you, not because I am perfect, but because you have claimed me. Amen.
