Exodus 36:13
And he made fifty taches of gold, and coupled the curtains one unto another with the taches: so it became one tabernacle. And he made fifty taches of gold, and coupled the curtains one unto another with the taches: so it became one tabernacle.
Fifty clasps of gold were made to couple the separate curtains one to another, so that the distinct parts were joined together and became one whole tabernacle. The joining was accomplished with exactness and skill, carried out according to the pattern God showed to Moses. This careful and exact work demonstrates the perfection and care required in every task done in God's service.
