Isaiah 6:2-3
2 Above [ma`al] it stood [amad] the seraphims [saraph]: each one [echad] had six [shesh] wings [kanaph]; with twain [shanayim] he covered [kacah] his face [paniym], and with twain [shanayim] he covered [kacah] his feet [regel], and with twain [shanayim] he did fly [uwph].
3 And one cried [qara] unto another, and said [amar], Holy [qadowsh], holy [qadowsh], holy [qadowsh], is the LORD [Yahovah] of hosts [tsaba]: the whole earth [erets] is full [malo] of his glory [kabowd]. KJV-Interlinear
2 Seraphim stood above Him, each having six wings; with two he covered his face, and with two he covered his feet, and with two he flew. 3 And one called out to another and said, 'Holy, Holy, Holy, is the LORD of hosts, The whole earth is full of His glory.' NASB
Here is referenced one of the three categories of angelic beings mentioned in the Bible - Cherubim, Seraphim, and Living Creatures.
The second category is mentioned here - Seraphim. The word for Seraph comes from their copper color, with a meaning of a burning or fiery serpent.
The numbers of the Seraphim are not mentioned however it is implied that they are many with the plural ending to the name.
Each Seraph has six wings. Two cover the face, two cover the feet, and the other two are used for their mobility.
There are a lot of speculations in commentaries, as to the meanings of the wings and the positions that they are in. Some suggesting that they cannot bear to see the glory of the Lord, or that their feet represent something less than honorable so they have to be covered, however the angels are higher than mankind at this point in history and Isaiah, in this vision is seeing the glory of the Lord, and Isaiah is the lessor creature in this vision.
Their covering is more representative of an acknowledgment of Gods glory which is far greater than anyone else's. This is a position of humility and respect more so than a position of embarrassment. Their glory is covered and not presumed so that only the glory of the Lord is in view here.
We'll see later on that Isaiah will offer his services to serve God, but the Seraph will bring a burning coal to remove the sin in him (Isaiah). So Isaiah's presumption is quickly squashed until he is cleansed of his sins. But more on that later on in our study.
Even though they subordinate themselves to God, they can still maneuver efficiently and effectively, and swiftly. They are not bound to one spot.
In contrast to the Seraphim that are mentioned here is Satan who is not mentioned here. Satan rejected God. Satan being in the Cherubim category, and being the highest of all the angels, did not subordinate himself to God, viewing himself as equal to or even greater than God.
Later in history man will be made greater than the angels and Satan who thought himself as high in the heavenly pecking order, will discover that despite all of his own glory, he will become a second class citizen (actually even lower) to the lowly humans on this planet.
The Seraphim sing out the glories to the Lord, Jesus Christ. They triple the phrase, possibly in recognition of the Trinity, but more likely since the Lord only is in view here, to His phenomenal perfection. Thus the tripling of the phrase, Holy, Holy, Holy. Gods glory appears in the Throne room, not mans, and not angels. Men and angels have no inherent glory to speak of. They only have the glory which God grants each person. All glory comes from God and from no other source.
Glory of course being the great honor, or praise, or distinction given by or earned by, or naturally inherent within the person and character of God.
Holiness is made up of the combination of Gods righteousness, and Gods justice. Righteousness is the absolute perfection of God, without blemish, without flaws, without sin of course, and justice is the perfect cleansing away of all the filth, or sin, or human righteousness from anyone before they can approach God.
The Lord is the commander of 'hosts,' or many categories of creatures. This would include the many different people from planet earth, and the many different classes of angels. Each group numbering into the many billions, and as far as angels go their numbers are never mentioned except that they are like the stars in the heavens. Today we know that there are billions of galaxies and billions of stars within each galaxy. So the numbers of angels is probably in the trillions of trillions of trillions plus. That should be classified as a very large number, I think. And all (except the fallen angels of course) voluntarily acknowledge Christ as Lord and God and the sovereign ruler.
The whole earth is full of Gods glory, always has been and always will be. Despite the attempts by those who reject God, who reject His work and evidence of His presence. The truth of God can never be wished away, nor reinvented or replaced by some other type philosophy or belief or religion. All other religions, beliefs, or philosophies on this earth, which are contrary to that which is taught in the Bible, are false, they are frauds, and they are nothing more than traps for destroying any who subscribe to them.
There is no place where you can go, no place where you can turn that you will not see some evidence of Gods handiwork. There is no one on this earth nor in all of history who hasn't come to know of or hear of the Lord. No one has any excuse.
