דברי הימים א, פרק ו׳, פסוק ב׳

The genealogical records of the tribe of Levi trace the family lines that eventually take on the sacred duties of the nation. As the record continues, it maps out the specific descendants of Gershom, detailing the next generation of this family tree.

Within this lineage, one of the sons is actually known by two different names in the historical accounts. The individual identified at this point as Libni is the exact same person referred to as Ladan later in the records [מצודת ציון]. This alternate name is used when the focus shifts to organizing the Levites, specifically when detailing the division of their work shifts for their formal service.
