covering: Exo 26:14
rams' skins dyed red: This was the third covering of the tabernacle. The first and lowermost was made of fine linen, richly embroidered with figures of cherubim, in shades of blue, purple, and scarlet - Exo 36:8-13. It is reasonable to suppose, that the right side of this curtain was undermost, and so it formed a beautiful ceiling in the inside of the tabernacle. The second covering, which lay over the embroidered one, was made of a sort of mohair - Exo 36:14-17, and the fourth, or uppermost one, which was to keep the others from the weather, was made of tachash, or badgers' skins.
