The word Angel means "Messenger" and is used in Scripture to describe the presence of Yeshua, angels, and men.  Yeshua appeared to men as the second person of the Trinity and the messenger of God (I Corinthians 10:4, 9; 11:3).  He is called the Angel of the LORD in (Genesis 16:7-11; 22:11,15; Exodus 14:19; Numbers 22:22-35; Judges 2:1,4; 6:11-12, 21-22; 13:3-6, 13-21; II Kings 1:3, 15; 19:35; I Chronicles 21:12-30; Psalms 34:7; 35:5-6; Isaiah 37:36; Zechariah 1:9-19; 3:1-6; 12:8; Acts 7:30-38).  Yeshua is also called the Angel of God in (Genesis 21:17; 31:11; Exodus 3:2; Judges 6:20; 13:9; Acts  27:23). 

Common angels are referred to in Psalms 104:4, "Who maketh his angels spirits; his ministers a flaming fire..."  In Revelation 1:1, 20; 2:1, 8, 12, 18; 3:1, 7, 14; 19:9, 10; 22:6-8,16 angels are referred to as men.

What are some of the characteristics of common angels?  They are heavenly spirit beings with distinct, personal souls/spirits, and physical bodies that were created by Yeshua at some point in the dateless past (Job 38:4-7; Psalms 148:2-5; Colossians1:16; Genesis 18:2, 4, 8; 19:1-22; Judges 13:6). They also possess a free-will, intelligence, passions, pride, appetites, etc. (Genesis 6:1-4; 18:8; 19:3; Ezekiel 28:17; I Timothy 3:6).

It should also be noted that angels are NOT demons (Acts 23:8-9).  Satan himself is a fallen angel who had the previous name of Lucifer.  "How art thou fallen from heaven, O Lucifer, son of the morning!  how art thou cut down to the ground, which didst weaken the nations!  For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God:  I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High.  Yet thou shalt be brought down to hell, to the sides of the pit" (Isaiah 14:12-15).     

Of all the myriads of angels that are mentioned in Scripture, there are only four angels that are specifically named:

   1.  Michael (Daniel 10:13, 21; 12:1; Jude 9;
        (Revelation 12:7)
   2.  Gabriel (Daniel 8:16; 9:21; Luke 1:19, 26)
   3.  Lucifer (Isaiah 14:12-14; Ezekiel 28:11-17)
   4.  Abbadon or Apollyon (Revelation 9:11)

Whenever believers find themselves in an impossible position, we can take heart in that we serve the same God who sent angels to deliver Daniel from the lions' den and Peter from prison (Daniel 6:22; Acts 5:19; 12:7-11).  We must believe the promises of Scripture that "the angel of the LORD encampeth round about them that fear him, and delivereth them," and that "he shall give his angels charge over thee, to keep thee in all thy ways" (Psalms 34:7; 91:11).
