Numbers 3:19 lists the sons of Kohath—Amram, Izehar, Hebron, and Uzziel—by their families. This verse identifies the main family branches descended from Kohath, one of the sons of Levi, as part of a census of the Levites.
This verse comes as God instructs Moses about organizing the Levites for their special duties related to the tabernacle. By naming these four sons, the text sets up the structure for how the Kohathite clan will be divided and assigned responsibilities. Each name represents a family group that will have a specific role among the Levites.
