And all the angels stood round about the throne (Isaiah 6)

Isaiah chapter six is a well-known chapter for this interesting vision that Isaiah has of God in Heaven (or is it the Temple in Jerusalem? I'm not sure...). I answered whether God can be seen in Genesis chapter twelve, and probably expanded on it elsewhere; the answer is no, but sometimes sort of. Isaiah is having a vision, and it may be not literally what God would look like, but how God allowed Isaiah to imagine him.

There is a lot of stuff that the SAB marks as absurd in this chapter, which is probably par for the course when it comes to supernatural visions. There's usually going to be strange things, and things not meant to be taken literally. While it's stated several times in the Bible that God has a throne in Heaven, since God doesn't have a physical body, it's not really clear what it means to see him sitting on it. Likewise, he doesn't likely have a robe with an enormous train as described here; it's probably simply symbolic of God's majesticness. Meanwhile, there are seraphim present ("seraphim" is already plural, so I sort of question "seraphims") which are a kind of angel, the Hebrew word meaning literally "fiery ones"; it's actually the same word translated as "fiery serpent" in Numbers 21:8! The seraphim have six wings, which, as stated, absurd or not, they only use one pair to fly with, while another pair covers their faces and the third covers their feet. This is an indication of how holy God is, as even angels hesitate to look directly at him. Also of course, as I mentioned a couple chapters back, they describe God as "Holy, holy, holy," the only instance of a word being repeated three times in the Bible other than the similar verse in Revelation. The seraphim are apparently shouting this so loudly the doorposts are shaking.

Isaiah is overwhelmed by all this glory and holiness, and expresses his unworthiness as "a man of unclean lips". This leads to an interesting moment where one of the seraphim brings a live coal and places it in Isaiah's mouth to cleanse him, and tells him his sin is gone (probably one of the oddest ways in the Bible of dealing with sin; does the SAB have a page on that?). Then God asks who he should send, which once again (although the SAB doesn't mark it here) doesn't mean God isn't omniscient, he already knows the answer, but is giving Isaiah a chance to volunteer, which he does. God tells Isaiah to tell the people of Judah that they hear but don't understand and see but don't perceive, and therefore God is going to shut their ears and eyes, and make their hearts not understand. The SAB marks this as unjust, but the idea here is that the people of Judah have been refusing to hear God for so long that he's going to let them continue to not hear to the point of destruction; this is a result of their own choices. Isaiah asks how long this will be, and God says it will be until Judah is desolate, but he will leave a tenth (I assume a tenth of the people, but it's not completely clear), which will also be somewhat desolate, but like a tree that loses its leaves, there will still be life there.
