John Wesley on Zechariah 3:9

Behold - Behold (pointing to a particular stone) that stone which I have laid in the sight of Joshua. Upon one stone - On that stone are seven eyes, probably so placed, that they may look many ways; so it was a more exact emblem of Christ, and of his perfect knowledge and wisdom. I have removed - I have pardoned the iniquity of this land at once. The temple, founded on such a corner - stone, guarded and watched over by all - seeing Providence, is the blessing and honour of that people, whose sins are all forgiven.
