1 Chronicles 6:30

And the sons of Samuel; the firstborn Vashni, and Abiah.

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

And these are they whom David set over the service of song in the house of the LORD, after that the ark had rest.

And they ministered before the dwelling place of the tabernacle of the congregation with singing, until Solomon had built the house of the LORD in Jerusalem: and then they waited on their office according to their order.
