1 Chronicles 23:5-7

Revised Geneva Translation

⁵ And four thousand were gatekeepers. And four thousand praised the LORD with instruments (“…which I made for praise!” said David).

⁶ So David separated the sons of Levi — Gershon, Kohath, and Merari — into divisions.

⁷ Of the Gershonites were Laadan and Shimei.
