2 Chronicles 29:13

The descendants of Elizaphan appear to have always formed a distinct branch of the Kohathites with special privileges (1 Chronicles 15:8). Elizaphan was a grandson of Kohath (Exodus 6:22) and was chief of the Kohathites at the time of the census in the wilderness (Numbers 3:30).
