Coverings of Tabernacle

Prophetic of:

Curtains of fine linen - RIGHTEOUSNESS
Inner layer | comprised actual roof or ceiling of sanctuary
Curtains of goat's hair - SIN OFFERING
Called "tent" | placed over fine linen curtain
Ram's skin dyed red - SUBSTITUTION
"a covering" | placed as third layer.
Outer covering of badger's skin - PROTECTION
Final covering | viewed to all the world that is outside

It is suggested that "badger skin" is dolphin or porpoise skin.
Badger skin had no particular beauty but protects against
weather, storms, desert heat, and the wilderness life of travel.
