1 Chronicles 23:4-5, 28-32

David said, “Of these, twenty-four thousand Levites will direct the work of the Temple of the LORD, six thousand Levites will be officers and judges, four thousand Levites will be gatekeepers, and four thousand Levites will praise the LORD with musical instruments I made for giving praise.”

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. The Levites also stood every morning and gave thanks and praise to the LORD. They also did this every evening. The Levites offered all the burnt offerings to the LORD on the special days of rest, at the New Moon festivals, and at all appointed feasts. They served before the LORD every day. They were to follow the rules for how many Levites should serve each time. So the Levites took care of the Meeting Tent and the Holy Place. And they helped their relatives, Aaron’s descendants, with the services at the Temple of the LORD.
