Look upon Zion, the city of our solemnities: thine eyes shall see Jerusalem a quiet habitation, a tabernacle that shall not be taken down; not one of the stakes thereof shall ever be removed, neither shall any of the cords thereof be broken.
Look upon Zion, the city of our solemnities - of our solemn assemblies at the great feasts (note, Isaiah 30:29; Psalms 42:4; Psalms 48:12).
A tabernacle (that) shall not be taken down; not one of the stakes thereof shall ever be removed - image from captives "removed" from their land (Isaiah 36:17). There shall be no more 'taking away' to an enemy's land. Or else, from nomad livers in shifting tents. The saints who sojourned once in tabernacles as pilgrims shall have a "building of God ... eternal in the heavens" (2 Corinthians 5:1; Hebrews 11:9-10: cf. Isaiah 54:2).
Stakes - driven into the ground: to these the "cords" were fastened. Christ's Church shall never fall (Matthew 16:18). So individual believers (Revelation 3:12).
