the descendants of Kohath. They formed the first of the three divisions of the Levites (Ex 6:16,18; Nu 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 (Nu 4). Their place in the marching and encampment was south of the tabernacle (Nu 3:29,31). Their numbers at different times are specified (Nu 3:28; 4:36; 26:57,62). Samuel was of this division.
