'Joined' in the Bible

There shall be two tenons in each board, joined to one another: thus you shall make for all the boards of the tabernacle.

It shall have two shoulder straps joined to the two ends of it, that it may be joined together.

Each board had two tenons, joined one to another. He made all the boards of the tabernacle this way.

They made shoulder straps for it, joined together. At the two ends it was joined together.
