1 Chronicles 23:27-32

27David’s last instructions were to count the Levites who were at least 20 years old.

28They were appointed to stand beside Aaron’s descendants to serve in the Lord’s temple. They were appointed to be in charge of the courtyards and the temple rooms, to ensure that all the holy things were clean, and to serve in God’s temple.

29They were also responsible for the rows of bread, the flour for the grain offerings, the unleavened bread wafers, and the bread made in frying pans. In addition, they were responsible for mixing the ingredients and keeping track of all weights and measures.

30They were appointed to stand to give thanks and praise to the Lord every morning. They were appointed to do the same thing in the evening.

31They were appointed to stand in front of the Lord in the required numbers whenever burnt offerings were made—on weekly days of rest—holy days, at New Moon Festivals, and on appointed annual festivals.

32They were appointed to follow the regulations for the tent of meeting and the holy place and to help their relatives, Aaron’s descendants, as they served in the Lord’s temple.
