1st Chronicles 16:39

36 Praise be to the Lord, the God of Israel, for ever and for ever. And all the people said, So be it; and gave praise to the Lord.

37 So he made Asaph and his brothers keep their places there before the ark of the agreement of the Lord, to do whatever had to be done before the ark at all times day by day:

38 And Obed-edom, the son of Jeduthun, and Hosah, with their brothers, sixty-eight of them, to be door-keepers:

39 And Zadok the priest, with his brothers the priests, before the House of the Lord in the high place at Gibeon;

40 To give burned offerings to the Lord on the altar of burned offerings morning and evening, every day, as it is ordered in the law of the Lord which he gave to Israel;

41 And with them Heman and Jeduthun, and the rest who were marked out by name to give praise to the Lord, for his mercy is unchanging for ever;

42 And Heman and Jeduthun had horns and brass instruments sounding loudly, and instruments of music for the songs of God; and the sons of Jeduthun were to be at the door.
