These verses give us the relation of the order respecting the psalmody in the house of the Lord. David himself is stilled, the sweet Psalmist of Israel: and it appears, from what is here said, that he presided in the choir of singers, and gave them their several stations. Some of the characters here mentioned, are noticed in the book of Psalms. Heman's name stands at the head of Psalms 88:1. Ethan at Psalms 89:1. Asaph at several, Psalms 73:1 to Psalms 83:1.
1 Chronicles 6:31-48
