1 Chronicles 23:28-29

28The Levites' work was to help Aaron's descendants as they served the Lord in his temple. They took care of the temple's yards and its small rooms. They made the Lord's special things clean and holy. They did the work that was necessary to serve God in his temple.

29They took care of the special bread for the table in the holy place. They kept the flour for the grain offerings, for the flat bread that they made without yeast and for the special cakes. They weighed and they measured all the things for the bread and the cakes.
