This prophetical passage about measuring the temple seems to refer to Ezekiel's vision. The design of this measuring seems to be the preservation of the church in times of public danger; or for its trial, or for its reformation.
The worshippers must be measured; whether they make God's glory their end, and his word their rule, in all their acts of worship. Those in the outer court, worship in a false manner, or with dissembling hearts, and will be found among his enemies.
God will have a temple and an altar in the world, till the end of time. He looks strictly to his temple. The holy city, the visible church, is trodden under foot; is filled with idolaters, infidels, and hypocrites.
But the desolations of the church are limited, and she shall be delivered out of all her troubles.
