1 Chronicles 15:5

the sons of Kohath: Uriel Kohath had four sons (Exodus 6:18 = 1 Chronicles 6:18) Amram, Izhar, Hebron, and Uzziel. Here the descendants of Amram (exclusive of the priests, the Aaronites) represented by Uriel head the list (1 Chronicles 15:5), and the descendants of Izhar, Hebron, and Uzziel appear in 1 Chronicles 15:8-10 respectively. Elizaphan(1 Chronicles 15:8), either stands for the Izharof Exodus 6:18, or is the name of some prominent descendant of Izhar after whom the whole family was named. As regards number the Kohathites were 512 against 350 of the sons of Merari and the sons of Gershom combined. In 1 Chronicles 6:60-63 (45 48 Heb. division) 23 cities are reckoned to Kohath against 25 to Merari and Gershom combined. The Kohathites formed the largest and most important of the three divisions of the Levites.
