1 Chronicles 23:28-29

The Levites had the job of helping Aaron’s descendants in the service of the Temple of the LORD. They cared for the Temple courtyard and side rooms, and they made all the holy things pure. Their job was to serve in the Temple of God. They were responsible for putting the holy bread on the table, for the flour in the grain offerings, for the bread made without yeast, for the baking and mixing, and for the measuring.
