We are part way through the seven trumpets of warning (chapters 7 – 11), the third of the seven scans of the gospel age that are in the Book of Revelation.

‘Measure them.’ For what purpose? To indicate that the dimensions of the temple are known. In other words, the holy place has been delineated by God. They are marked out for special protection. Measure the holy of holies and the holy place; delineate them; identify them – they will be under the special protection of God.
