1 Chronicles 6:29-32

29The sons of Merari were Mahli, Libni his son, Shimei his son, Uzzah his son,

30Shimea his son, Haggiah his son, and Asaiah his son.

31Now these are the men whom David appointed over the service of song in the house of the Lord, after the ark came to rest.

32They were ministering with music before the dwelling place of the tabernacle of meeting, until Solomon had built the house of the Lord in Jerusalem, and they served in their office according to their order.
