Zech 3:9

9 For, behold, the stone that I have set before Joshua; on one stone are seven eyes: behold, I will engrave the engraving of it,’ says Yihvah of Hosts, ‘and I will remove the iniquity of that land in one day.

upon the stone are seven eyes – these are the Seven Spirits in the hand of the Spirit of Christ, as the Archangel; these are the Spirits we first saw reporting to the Angel of Yihvah in Zech 1:10. These Spirits go to and fro throughout the earth, as we read in Zech 4:10, Rev 5:6, etc. They are called the eyes of Christ.

I will engrave an inscription on it – the inscription can only refer to the “new name” on the “white stone”  in Rev 2:17. White has the meaning of holiness or purity in the Bible, for example the White horses in Rev 6:2, and Rev 19:11, are the Angels of God. The saints have their sins washed away in one day, as described below, and they receive a “new name,” a new reputation.

and I will remove the iniquity of the land in one day – in “one day,” by the death of Christ who paid the price for all sin.
