'Joining' in the Bible

joining one unto another are their wings, they turn not round in their going, each straight forward they go.

And their faces and their wings are separate from above, to each are two joining together, and two are covering their bodies.

Then, joining them one to another, make them one stick, so that they may be one in your hand.

And I have looked at the house, the height all round about: the foundations of the side-chambers are the fulness of the reed, six cubits by the joining.
