2. Mose 26:4

They were also to make 50 hyacinth loops "on the border of the one piece of tapestry, from the end in the join," i.e., on the extreme edge of the five pieces that were sewed together; and the same "on the border of the last piece in the second joined tapestry." Thus there were to be fifty loops in each of the two large pieces, and these loops were to be מקבּילת "taking up the loops one the other;" that is to say, they were to be so made that the loops in the two pieces should exactly meet.

Moses here receives instructions, I. Concerning the inner curtains of the tent or tabernacle, and the coupling of those curtains (Exo 26:1-6). II. Concerning the outer curtains which were of goats' hair, to strengthen the former (Exo 26:7-13). III. Concerning the case or cover which was to secure it from the weather (Exo 26:14). IV. Concerning the boards which were to be reared up to support the curtains, with their bars and sockets (v. 15-30). V. The partition between the holy place and the most holy (Exo 26:31-35). VI. The veil for the door (Exo 26:36, Exo 26:37). These particulars, thus largely recorded, seem of little use to us now; yet, having been of great use to Moses and Israel, and God having thought fit to preserve down to us the remembrance of them, we ought not to overlook them. Even the antiquity renders this account venerable.
