Seraphim

Boyd’s Bible Dictionary:

Concise Bible Dictionary:

Symbolical celestial beings seen by Isaiah standing above the Lord on His throne (Adonai, but many MSS read Jehovah). Each had three sets of wings: with one pair he covered his face, in token of reverence; with another he covered his feet, in token of humility; and with the third he flew to accomplish his mission.
Gesenius and Fürst give to the word saraph the meanings “to burn,” and “to be exalted.” They trace the seraphim to the latter signification, as “exalted ones.” The word occurs only in Numbers 21:66And the Lord sent fiery serpents among the people, and they bit the people; and much people of Israel died. (Numbers 21:6); Deuteronomy 8:1515Who led thee through that great and terrible wilderness, wherein were fiery serpents, and scorpions, and drought, where there was no water; who brought thee forth water out of the rock of flint; (Deuteronomy 8:15), translated “fiery;” and in Numbers 21:88And the Lord said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live. (Numbers 21:8); Isaiah 14:2929Rejoice not thou, whole Palestina, because the rod of him that smote thee is broken: for out of the serpent's root shall come forth a cockatrice, and his fruit shall be a fiery flying serpent. (Isaiah 14:29) and Isaiah 30:66The burden of the beasts of the south: into the land of trouble and anguish, from whence come the young and old lion, the viper and fiery flying serpent, they will carry their riches upon the shoulders of young asses, and their treasures upon the bunches of camels, to a people that shall not profit them. (Isaiah 30:6), translated “fiery serpent.” In Isaiah 6:2-72Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly. 3And one cried unto another, and said, Holy, holy, holy, is the Lord of hosts: the whole earth is full of his glory. 4And the posts of the door moved at the voice of him that cried, and the house was filled with smoke. 5Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts. 6Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar: 7And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged. (Isaiah 6:2‑7) (the plural) the seraphim are exalted beings, but the only actions recorded there are that one brought a live coal from off the altar and laid it upon the prophet’s mouth, and said, “Thine iniquity is taken away, and thy sin purged.” They cried to one another, “Holy, holy, holy is Jehovah of hosts; the whole earth is full of his glory.”
The distinction between seraphim and cherubim may be that, while the former bear witness to God’s holiness (that is, to His nature), in the latter are exhibited the principles of His righteous government on the earth. The “living creatures” of Revelation 4 combine the characteristics of both cherubim and seraphim.
