1 Chronicles 23:3-5

3His officers counted all the Levites who were 30 years old or older. There were 38,000 men.

4David said, ‘24,000 of these Levite men must have authority for the work of the Lord's temple. 6,000 of them will be officers and judges.

54,000 of them will be guards at the gates of the temple. 4,000 of them will use music to praise the Lord. They will use the musical instruments that I have provided for them.’
