Numbers 3:30

And the chief of the house of the father of the families of the Kohathites shall be Elizaphan the son of Uzziel.

Elizaphan the son of Uzziel was the designated chief over the families of the Kohathites. His appointment belonged to the ordered service of the Levites around the tabernacle, in which each division received its specific place in the camp and its assigned duty. The Kohathites were stationed to camp on the south side of the tabernacle. Their charge was the ark and its other furnishings.
