1 Tawarikh 23:13

23:13 The sons of Amram:

Aaron and Moses.

Aaron and his descendants were chosen on a permanent basis to consecrate the most holy items, to offer sacrifices before the Lord, to serve him, and to praise his name. ² 

[15:22]  ¹ tn Heb “and Kenaniah, the leader of the Levites, with lifting up, supervising with lifting up, for he was well-informed.” The precise nuance of מַשָּׂא (masa’, “lifting up”) is unclear. Some understand it as a reference to supervising the singing and music (e.g., NIV: “Kenaniah…was in charge of the singing”; NEB: “Kenaniah…was precentor in charge of the music”).

[23:13]  ² tn Heb “and Aaron was set apart to consecrate it, the most holy things, he and his sons, permanently, to sacrifice before the Lord, to serve him, and to bless his name permanently.”
