Joshua the high priest typifies Christ as the High Priest sent by God to His people (Heb. 3:1; 4:14-15; 7:26). Joshua also represents and signifies Israel as a nation of priests (Exo. 19:6; Zech. 8:20-23; Isa. 2:2-4a).
Joshua was standing before the Angel of Jehovah to be perfected, established, and strengthened in the priesthood (vv. 1-10). The Angel of Jehovah would do this by measuring Joshua. Christ’s care for Joshua in this chapter is a continuation of His measuring in Zech. 2:1-2.
