Angel is a word signifying, both in the Hebrew and Greek, a “messenger,” and hence employed to denote any agent God sends forth to execute his purposes. It is used of an ordinary messenger (Job 1:14: 1 Sam. 11:3; Luke 7:24; 9:52), of prophets (Isa. 42:19; Hag. 1:13), of priests (Mal. 2:7), and ministers of the New Testament (Rev. 1:20).
