Types Of Angels

TYPES OF ANGELS
The Angel of the Lord: The reference to that angel of the Lord is often used in a way that suggests it to be a manifestation of God Himself. For example, in Genesis 31:11-13, the angel of the Lord appears to Jacob in a dream and identifies Himself as “the god of Bethel.” Similarly, in Exodus 3:2 the angel of the Lord appears to Moses in the burning bush and identifies Himself in Exodus 3:6 as the God of Abraham, Isaac and Jacob.

Cherubim: This is the plural form of the singular “cherub.” Modern English has rendered this term to conjure up an image of a winged baby with fat little cheeks, but the Hebrew carries no such idea. The Hebrew bWrK. seems to be related to the Akkadian verb, “to bless.” [3]

Seraphim: The seraphim are mentioned only in Isaiah 6:1-13. The Hebrew term @r;F' (saraph) means “to burn.” These are therefore the “burning ones.” This is in keeping with the description of Hebrews 1:7 where the Lord is seen as the one who makes His angels winds, and His ministers a flame of fire.
