Exodus 26:11

And thou shalt make fifty taches of brass
As these curtains were coarser, and also the loops, so the taches, hooks, or clasps, were made of meaner metal, but answered the purpose of joining and coupling together full as well: and put the taches into the loops; one end of the hook or clasp into the loop on one of the curtains, and the other end of the hook or clasp into the loop on the other curtain answering to it: and couple the tent together, that it may be one; that the tent or covering over the tabernacle might be one, as the tabernacle by the like means was, ( Exodus 26:6 ) .
