1 Chronicles 6:29-32

29The sons of Merari: Mahli; Libni his son, Shimei his son, Uzza his son,

30Shimea his son, Haggijah his son, Asaiah his son.

31And these are they whom David set over the service of song in the house of Jehovah after that the ark was in rest.

32And they ministered before the tabernacle of the tent of meeting with singing, until Solomon had built the house of Jehovah in Jerusalem; and they attended to their office according to their order.
