By skipping down to verse 8, I am dodging some interesting speculations about who this Joshua is. But, I would rather point out some connections to Revelation that should be even MORE intriguing than this High Priest named Joshua.
8 Hear now, O Joshua the high priest, thou and thy fellows that sit before thee; for they are men that are a sign: for, behold, I will bring forth my servant the Branch.
9 For, behold, the stone that I have set before Joshua; upon one stone are seven eyes: behold, I will engrave the graving thereof, saith Jehovah of hosts, and I will remove the iniquity of that land in one day.
10 In that day, saith Jehovah of hosts, shall ye invite every man his neighbor under the vine and under the fig-tree.
Again, these verses are encapsulated within the Ezekiel Tetrad. All of this will happen then.
But, what are these seven eyes?
Revelation 5:5 and one of the elders saith unto me, Weep not; behold, the Lion that is of the tribe of Judah, the Root of David, hath overcome to open the book and the seven seals thereof.
Revelation 5:6 And I saw in the midst of the throne and of the four living creatures, and in the midst of the elders, a Lamb standing, as though it had been slain, having seven horns, and seven eyes, which are the seven Spirits of God, sent forth into all the earth.
Zechariah 4:10 For who hath despised the day of small things? for these seven shall rejoice, and shall see the plummet in the hand of Zerubbabel; these are the eyes of Jehovah, which run to and fro through the whole earth.
So, these seven eyes are the seven Spirits of God that are sent into all the earth. That’s a bit more information, but not much more.
There certainly is more in heaven and earth than is explained in the bible. Much more.
