1 Chronicles 23:27-32

27According to David’s final instructions, the Levites twenty years old and up were counted.

28Their job was to help Aaron’s descendants in the service of the Lord’s temple. They were to take care of the courtyards, the rooms, ceremonial purification of all holy items, and other jobs related to the service of God’s temple.

29They also took care of the bread that is displayed, the flour for offerings, the unleavened wafers, the round cakes, the mixing, and all the measuring.

30They also stood in a designated place every morning and offered thanks and praise to the Lord. They also did this in the evening

31and whenever burnt sacrifices were offered to the Lord on the Sabbath and at new moon festivals and assemblies. A designated number were to serve before the Lord regularly in accordance with regulations.

32They were in charge of the meeting tent and the holy place, and helped their relatives, the descendants of Aaron, in the service of the Lord’s temple.
