Kohathites

the descendants of Kohath. They formed the first of the three
divisions of the Levites (Ex. 6:16, 18; Num. 3:17). In the
journeyings of the Israelites they had the charge of the most
holy portion of the vessels of the tabernacle, including the ark
(Num. 4). Their place in the marching and encampment was south
of the tabernacle (Num. 3:29, 31). Their numbers at different
times are specified (3:28; 4:36; 26:57, 62). Samuel was of this
division.
