1 Chronicles 23:25–31

²⁵David had said, “The Lord God of Israel has given his people rest. He will now live in Jerusalem forever. ²⁶The Levites will no longer have to carry the tent and all the utensils used in worship.” 

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,^band 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.
