Exodus 26:12-14

Young's Literal Translation

¹² `And the superfluity in the curtains of the tent -- the half of the curtain which is superfluous -- hath spread over the hinder part of the tabernacle;

¹³ and the cubit on this side, and the cubit on that, in the superfluity in the length of the curtains of the tent, is spread out over the sides of the tabernacle, on this and on that, to cover it;

¹⁴ and thou hast made a covering for the tent, of rams' skins made red, and a covering of badgers' skins above.
