1 Chronicles 23:18

23:18 The son ¹  of Izhar:

Shelomith the oldest.

Exodus 6:21

6:21 The sons of Izhar were Korah, Nepheg, and Zikri.

Numbers 3:19

3:19 The sons of Kohath by their families were: Amram, Izhar, Hebron, and Uzziel.

Numbers 3:27

The Numbering of the Kohathites

3:27 From Kohath came the family of the Amramites, the family of the Izharites, the family of the Hebronites, and the family of the Uzzielites; these were the families of the Kohathites. ² 

[23:18]  ¹ tn The Hebrew text has the plural “sons,” but only one name appears after this. The attached phrase “the oldest” might indicate that Shelomith was not Izhar’s only son, but note v. 17.

[3:27]  ² sn Both Moses and Aaron came from this line (6:16-20). During the Hebrew monarchy this branch of the line of Levi was exemplary in music (1 Chr 6:33-48). They were also helpful to Hezekiah in his reforms (1 Chr 29:12-14).
