What is the meaning of the eyes on the stone with seven eyes?

“For, see, the stone that I have set before Joshua, on one stone are seven eyes. Behold I will engrave its engraving, says Yahweh of hosts, and I will remove the iniquity of the land in one day.”

The crowning of Joshua has been highly symbolic. It has pointed forward to the Messianic king. The stone mentioned here is that set in the High Priest’s turban. The seven eyes are ‘the eyes of Yahweh, they run to and fro through the whole earth.’ (4.10). They emphasis that in the Branch God will fulfil His universal purpose, and that God will watch over His concerns.

‘Behold I will engrave its engraving.’ Its engraving was ‘holy to Yahweh’ (see on 3.5). So God’s promise is that He Himself will personally make the Branch, of whom Joshua is a sign and symbol, ‘holy’ to Himself, set apart and treasured. He Himself will engrave His own personal mark upon Him.

‘And I will remove the iniquity of the land in one day.’ The purifying of Joshua (3.4-5) is symbolic of a greater day when the iniquity of the land will be dealt with at a stroke. Then (as we now know, through the death of the chosen Messiah) a fountain will be opened for sin and uncleanness (13.1).
