'Reu,' as in Genesis 11:18, signifies a more external form of worship than that signified by 'Peleg,' his father.

In Revelation 21:3, Joshua 22:19, and elsewhere, 'Tabernacle' means the same thing as 'temple,' except that 'temple' means the Lord's divine humanity with respect to divine truth, or divine wisdom, and 'tabernacle' means the Lord's divine humanity with respect to divine good or divine love. 'The Tabernacle of God,' as in Revelation 21:3, signifies the celestial church. In a universal sense, it signifies the celestial kingdom of the Lord, and in the highest sense, the divine humanity of the Lord.
