Hebrews 1:6-7 And again, when he brought in the firstbegotten into the world, he said, And let all the angels of God worship him. And of the angels he said, Who made his angels spirits, and his ministers a flame of fire.
There are ten kinds of spirit beings besides God (continues): [6] Common angels (Gen. 18:2, 4, 8; 19:1-22; Num. 22:22-35; Jdg. 13:6; 2Sam. 14:20; 19:27; Ps. 103:20; Isa. 37:36; Matt. 6:10; 24:36; Mark 8:38; 13:32; Luke 9:26; 20:36; 1Cor. 11:10; Eph. 3:10; 1Pet. 1:12; 2Pet. 2:11; Jude 1:9; Rev. 18:1, etc.). [7] Demons ((Lev. 17:7; 19:31; 20:6; Deut. 18:11; 32:17; 1Sam. 28:3, 9; 2Kin. 21:6; 23:24; 2Chron. 11:15; Ps. 106:37; Isa. 8:19; 19:3). [8] Demonic locusts (Rev. 9:1-11). [9] Demonic horsemen (Rev. 9:12-21). [10] The inner man, or soul and spirit of human beings.
Definition and usage of “Angel”: The word literally means messenger and is used for Christ, angels, and people. [1] Christ, the second Person of the Trinity appeared to men as the messenger of God (1Cor. 10:4, 9; 11:3). He is called: (1) The angel of God (Gen. 21:17; 31:11; Ex. 3:2; Jdg. 6:20; 13:9; Acts 27:23). (2) The angel of the Lord (Gen. 16:7-11; 22:11, 15; Ex. 14:19; Num. 22:22-35; Jdg. 2:1, 4; 6:11-12, 21-22; 13:3-6, 13-21; 2Kin. 1:3, 15; 19:35; 1Chron. 21:12-30; Ps. 34:7; 35:5-6; Isa. 37:36; Zech. 1:9-19; 3:1-6; 12:8; Acts 7:30-38). In all other places where “the angel of the Lord” is found, the term refers to ordinary angels, as in Matthew 1:20, 24; 2:13, 19; 28:2-5; Luke 1:11-38; 2:9-21; Acts 5:19; 8:26; 10:3; 12:7-23. (3) His angel (Gen. 24:7, 40; Ex. 23:20; 33:2; Num. 20:16; 2Chron. 32:21; Dan. 3:28; 6:22). (4) The angel (Gen. 48:16; Eccl. 5:6; Hos. 12:4). (5) Mine angel (Ex. 23:23; 32:34). (6) Angel of His presence (Isa. 63:9). (7) Angel (Rev. 8:3-5; 10:1-11:3). [2] The word angel is used for common angels in Psalms 104:4. [3] It is used of men in Revelation 1:1, 20; 2:1, 8, 12, 18; 3:1, 7, 14; 19:9, 10; 22:6-8, 16. In other places, it is nearly always clear that common angels who are spirit beings and heavenly creatures are referred to.
