Exodus 36:19 kjv — And he made a covering for the tent of rams’ skins dyed red, and a covering of badgers’ skins above that.

And he coupled five curtains by themselves, and six curtains by themselves.

And he made fifty loops upon the uttermost edge of the curtain in the coupling, and fifty loops made he upon the edge of the curtain which coupleth the second.

And he made fifty taches of brass to couple the tent together, that it might be one.

And he made boards for the tabernacle of shittim wood, standing up.

The length of a board was ten cubits, and the breadth of a board one cubit and a half.

One board had two tenons, equally distant one from another: thus did he make for all the boards of the tabernacle.
