“As participants in God’s heavenly council, they contribute to council resolutions, bear witness to his decrees, and assist in his governance of the world (33–46). They also deliver his decrees, explain his activity, and execute his judgment (46–55). They’re both the “heavenly bureaucracy” (13) and “God’s task force” (56). And perhaps most familiarly, they’re God’s heavenly worship team, praising him day and night (55–56).”
