1. Porters. Chapter 26 deals with the 24 courses of porters or warders ( 1-19), the overseers of the treasures of the sanctuary ( 20-28), and the officials charged with “outward business over Israel,” such as officers and judges ( 29-32).
Asaph. This is not the Asaph of 25:2, who was a Gershonite ( 6:39-43). The Korhites, descendants of Korah, were Kohathite Levites (Ex. 6:18, 21; Num. 16:1).
