Moreover you shall make the tabernacle with ten curtains of fine twined linen, and blue, and purple, and scarlet: with cherubim of skillful work shall you make them.
All Commentaries on Exodus 26:1 Go To Exodus 26
Gregory The Dialogist
AD 604
Surely no access to the heavenly city is given us if we do not keep the love of God and neighbor in this church, which because it is outside is called a porch. This is why it was ordered that the curtains of the tabernacle be woven from scarlet cloth twice dyed. You, my friends, you are the curtains of the tabernacle, since by your faith you veil the heavenly secrets in your hearts. Scarlet twice dyed must be used for the curtains of the tabernacle. Scarlet has the look of fire, and what is love but fire? This love must be twice dyed, dyed by love of God and dyed by love of our neighbor.
